Jack Grealish finds his goalscoring touch, Nico O'Reilly shines in an unfamiliar role, and Kalvin Phillips shows his versatility: FIVE THINGS WE LEARNED as Man City lose on penalties to Barcelona

Manchester City fell to a third successive defeat on their US pre-season tour, losing 4-1 on penalties to Barcelona following a thrilling 2-2 draw in Orlando, Florida, on Wednesday night.

Kalvin Phillips saw his spot kick saved in the shootout as City failed to convert two of their three penalties, while the Catalonian side tucked away all four for the victory.

The Spanish giants took the lead midway through the first half after Pau Victor fired a low finish beyond Ederson, but they were pegged back 15 minutes later following a fantastic strike from the boot of Nico O’Reilly.

Barcelona did re-take the lead in first-half stoppage time through Pablo Torre, however, Jack Grealish finished off a sweeping counter-attack after the break before ultimately losing via the shootout.

Here, Mail Sport's Jack Gaughan takes you through five things we learned from Florida.

O'Reilly playing his way into Guardiola's plans?

Oscar Bobb’s taken the real shine away from anybody else on this tour but Nico O’Reilly certainly deserved his moment against Barcelona.

He rose to prominence when scoring a scorpion kick for the academy two years, and then following it up with a stunning lob in an Under-18 derby days later.

He’s had to bide his time for an opportunity to impress Pep Guardiola and has taken it over the past 10 days.

O’Reilly’s clever forward run carved out a Bobb goal against Celtic and it was his turn to finish off a smart move here in Orlando.

The 19-year-old sauntered beyond Barca’s back line and picked up an incisive Josko Gvardiol through ball to slot beyond Ignacio Pena. It even drew applause from Erling Haaland so can’t have been bad.

And his overall performance, playing a little deeper than usual, was full of strong moments in the tackle and a good range of passing. The odd little mistake here and there but to be expected.

O’Reilly – represented by the same agency as Guardiola - will hope he is given some cup games this season to show more in competitive fixtures.

Mixed evening's for the Croatian duo

The two Croatians, Gvardiol and Mateo Kovacic, are playing a bit of catch up after arriving in New York and feeling their way into pre-season.

Both had their moments in Orlando. Kovacic in particular sems like he’s never been away, gliding through midfield on his first 65-minute appearance back.

And the way he took six Barca players out of the game during a powerful 70-yard run for Jack Grealish’s goal show that he is more than just a credible rotational option to Rodri.

That central midfield area will be crowded given Phil Foden and Bernardo Silva but Kovacic’s performances towards the end of last season make him difficult to dislodge.

Gvardiol had more of a mixed evening. There were lapses in concentration at centre half – his natural position but one he barely operates in anymore – and his impatient press led to Barca’s opener. But then the pass for O’Reilly’s strike served as a reminder of his quality in possession.

Grealish shows his goalscoring threat

Even before his goal, Grealish was acting with a bit more of an edge in this friendly. More willing to run at his man and seemingly more in tune with those around him.

The finish will have done him good, owing much to the aforementioned Kovacic burst. A confident finish across the goalkeeper on his left foot after settling himself.

He admitted to us earlier in the week that the England snub was the hardest moment of his career and has something to prove ‘to some people’. Gareth Southgate being one of them, you presume.

Grealish has been criticised for a lack of goals and assists since joining City for £100million yet does also know his value within Guardiola’s team.

‘I want to score, because in football there is no better feeling than scoring goals, but it is a team game,’ he said a few months back after an encouraging display at Crystal Palace.

‘I feel I bring so much more to the team than just goals and assists. If you watch the Palace game back you'll see I played well. It's just a shame that everyone in the world now just loves stats.’

He’s not wrong but a few more goals like this wouldn’t hurt.

A new position for Phillips? 

Barcelona, a sell-out 63,237 crowd, did Guardiola overthink the occasion? Don’t write in. It’s a joke.

An inventive call at the back though, which became clear when Kalvin Phillips was doing drills as a centre back in training 24 hours beforehand.

And Phillips did well there, next to Gvardiol. More time on the ball, that extra second to pick his pass, and he seemed far more comfortable. Defensively solid too. Perhaps some food for thought for the England international.

Elsewhere, Maximo Perrone was a false nine for a spell and Jaden Heskey – son of Emile – showed glimpses of real potential during a short cameo.

A reminder that technology is needed 

There is often that phenomenon of players becoming better for not actually featuring and that was definitely true of technology during this.

Haaland looked certain to have given City an 11th-minute lead when the Norwegian stretched a limb to divert Oscar Bobb’s cross home.

Barcelona goalkeeper Pena did well in scrambling to get something behind the effort but didn’t seem to prevent it going behind the line.

Replays showed that it appeared to have crept across but the linesman, who was stood behind the goalkeeper’s body, didn’t see it.

With no goal line technology, we played on and Barca took the lead 13 minutes later. Although none of that mattered on the night, a reminder that some technology does enhance proceedings.

On Haaland, it’s interesting that Guardiola has opted to substitute the striker at half time of the last two friendlies while others stay on midway into the second half. ‘Erling has already rested,’ Guardiola said last week. ‘(If) he’s tired, go to bed early. Focus 24 hours and you will be ready. Tiredness is not an excuse. I push him to be more focused.’
