It's the biggest decision of Gareth Southgate's life... and I'm afraid he needs to drop Harry Kane, writes GRAEME SOUNESS

Gareth Southgate faces the biggest football decision of his life on Saturday: whether to drop Harry Kane.

If he gets it right, it is a decision that will make Gareth a national hero and, on current evidence, I'd say you have to leave Harry out.

I've been one of Harry's greatest supporters. He is a fantastic goalscorer, who has shown terrific ability at Tottenham, Bayern Munich and for England but this tournament he has looked like he is towing a caravan around the football pitch.

The introduction of Ollie Watkins against the Netherlands enlivened the team. Park the fact he scored a wonderful goal, his contribution changed England as an attacking threat.

Gareth has been fiercely loyal to Harry, often with good reason as he has been a matchwinner on many occasions, and as I've said before I wouldn't like to begin to second guess what England's manager does next, but he has to seriously consider this change.

Watkins brought so much better energy to England when they didn't have possession.

Your press starts with how the man closest to the ball reacts. Watkins was sprinting after the ball. I know he was only on for 15 minutes, but he plays like that every week for Aston Villa too. I'm not just basing this on the winning goal against Holland, I'm taking into context Harry's all-round performances in the past six games.

Would it give the opposition a lift not to see his name on the team-sheet? I'm not so sure. Harry is a craftsman with an eye for goal, but England need more than he is offering lately against Spain.

The thing defenders worry about facing most is real pace. A defender hates it when you are constantly turning them, taking them back towards their own goal. They love to see a centre forward stood right in front of them all the time and that is what Harry has become in these six games - all too easy to play against.

In his defence, Harry will feel that he doesn't get the ball quick enough and there is too much passing sideways and backwards from his teammates. So often, he has been the talisman and you have to wonder if he is carrying an injury that we don't know about.

But ultimately, he has not brought his early Bayern Munich form; he's not been creative enough and he's not been dripping in goals from open play. Watkins' willingness to run in behind was a reminder of what you can achieve with good forward movement because England have players such as Cole Palmer who can hit the striker with the kind of slide rule pass of unerring accuracy that he delivered for the winning goal on Wednesday.

This is a one-off chance that England have to seize.

If they win this, in years to come they won't be showing the grandkids the highlight reel from the first five games, it'll be the semi-final then final only because the rest hasn't been worth watching.

I said before the Euros started that England were my favourites and that this was their best chance of winning a tournament since 1966, but the way they have played you would never have expected them to reach the final.

Up until the semi-final, the performances have been miserable, with no excitement, but they have shown that great British trait of being dogged. And, when the chips are down and we feel the world is against us, we come together and like to prove people wrong.

England were better against the Netherlands because they weren't facing a team that wanted to sit in. The Dutch wanted to attack because they fancied their chances, yet England dug in and fair play to them got the result. That in itself is a sign of big players having the right mentality. You can bet your bottom dollar though, that if Holland fancied their chances, Spain will do so even more.

They are a very, very good team yet Spain will try and be on the front foot for the full 90 minutes which could be tailor-made for England because we can't forget they still have some excellent attacking players. It's worth remembering that Spain lost 2-0 to Scotland at Hampden just over a year ago so they are not invincible.

What I do hope is that both teams let loose and we see a real spectacle.

These Euros have not been a footballing festival easy on the eyes so it would be good to see a final befitting a top tournament.

Spain are the favourites, but they are certainly not unbeatable. England, with their players, should have no fears, they have to adopt that mentality to finally win this tournament for the first time.

Yamal's a real unicorn... he should not be so good at 16

I almost have no words for Lamine Yamal. No-one should be that good at 16 years of age. I can only describe him as a 'unicorn', an almost fictional character that shouldn't really exist.

It's one thing to have dribbling skills and being able to run around but it's the maturity he shows in his choice of pass, in his decision-making. I can't remember seeing anyone like him at that age.

It will certainly be an intriguing contest to see him up against Luke Shaw.

There have been question marks over his selection with what he has been able to contribute to the tournament but Shaw must start against Spain. A hamstring injury can be the most unpredictable of injuries for a footballer but, without being too brutal, he must play against Yamal and, if he pulls up, then it is not Gareth Southgate's problem.

That would be Manchester United's to argue and that thought shouldn't be entering the England manager's head. Needs must and England need to play their best left-back.

Bellamy and I didn't see eye to eye, but I only wish him well 

Craig Bellamy and I didn't always see eye to eye but I only wish him well as he becomes the new manager of Wales.

The reasons we clashed were because Craig was often so desperate to be successful but I believed his actions were sometimes misguided. Regardless, I do wish him well as he takes on a great challenge.

It is also good to see another of my former players Scott Parker getting a chance to resurrect his career in England with Burnley.

Scott is a man you would always want in the trenches alongside you and I hope he can bring new success to Turf Moor.

My life laid bare in my new Mail podcast

I'm pleased to tell you that a Daily Mail podcast series which I think tells the real and unvarnished story of my life, with nothing left out and no questions ducked, will be released on August 1.

In some ways, I have found going back into the past for the series quite therapeutic! The series will shed new light on some of the events and experiences which have shaped my life and career. 

There are five podcasts in the series, which is called ‘Everything I Know About Me.’
