THE NOTEBOOK: Arsenal make the most of absent Bayern fans after warning to touts, Gunners reach Champions League milestone... while Harry Kane breaks an Emirates record

Harry Kane was denied a fairytale return to north London as Arsenal hit back to claim a 2-2 draw from an exhilarating Champions League quarter-final first leg with Bayern Munich.

Tottenham's all-time record scorer claimed his 15th career goal in 20 appearances against the Gunners by converting a first-half penalty to put the German club on course for victory at a raucous Emirates Stadium.

But substitute Leandro Trossard left the tie perfectly poised ahead of next week's return match with a 76th-minute equaliser after Bukayo Saka's early opener was cancelled out by former Arsenal forward Serge Gnabry.

Six-time European champions Bayern almost snatched a 90th-minute winner when Kingsley Coman struck a post, while Saka was denied an added-time spot-kick following a challenge from Manuel Neuer in a breathless finale.

Mail Sport's ISAAN KHAN takes a look at some of the things you may have missed.

Arsenal makes most of absent Bayern fans

Arsenal were eager to make the most of an Emirates full solely of home fans, as Bayern Munich were banned by UEFA from bringing supporters.

This was because of the German fans’ use of fireworks in the competition earlier this season. Posts featuring the phrases ‘full house’, ‘all red’ and ‘wear red’ were pumped out by the Gunners’ X account before kick-off to fire up the atmosphere.

One of the instructions for fans was that they could buy a matchday programme featuring a ‘special all-red cover’ to hold up to help ‘generate a brilliant visual’. 

Adding to the atmosphere was a volley of fireworks that were set off outside the ground during the first half by persons unknown.

Extra security after ISIS threat

An announcement from a media channel used by terror group ISIS, threatening attacks on the four stadiums hosting Champions League quarter-final ties, caused understandable concern.

So much so that Arsenal and the Metropolitan Police released statements to reassure supporters of their safety at Tuesday night’s match.

Police presence at the Emirates was visibly increased in a sign that these threats were not taken lightly.

Deputy Assistant Commissioner Ade Adelekan said: ‘I want to reassure the public that we have a robust policing plan in place for tonight’s match.’

Arsenal reach Champions League milestone

Not only was this Arsenal’s first match in the Champions League quarter-finals since 2010 but also the north London club’s 200th match in the competition. 

It all started back in September 1998 when they played Lens. 

Their three heaviest defeats all came against the same team — Bayern Munich, 5-1 each time. 

Gunners on alert

Arsenal were on alert for any supporters touting their tickets to opposition fans.

On Monday the club had threatened to ban anyone caught doing so. 

Precautionary measures included not selling tickets to any new members who registered for the ticket ballot after March 11, in advance of the last-eight draw. 

Before kick-off, the club also sent emails to fans suspected of selling their tickets, telling them to collect them from the box office with identification to hand. 

Who else but Harry Kane?

Predictably the mention of Harry Kane on the stadium tannoy sparked a torrent of boos. 

Former Spurs team-mate Eric Dier attracted a few and ‘Are you Tottenham in disguise?’ was chanted after Bukayo Saka’s opener. 

But Kane silenced the crowd, with his penalty his sixth goal at the Emirates — more than any other visiting player to the stadium. 

Clinical Bayern stun the Emirates 

Bayern Munich gave Arsenal a lesson in clinical finishing in the first half, scoring with their first two shots on goal to leave the Emirates stunned.
