Ajax fans were out in force in central London ahead of their Champions League clash with Tottenham on Tuesday.

Pictures and video on social media show Leicester Square being brought to a standstill by the Dutch supporters.

One shirtless fan climbed some scaffolding and proceeded to open a can of beer and sprayed it in the air.

A video posted by the club’s Twitter account shows a sea of Ajax fans in the centre of the city enjoying the sights ahead of the semi-final match.

One Tottenham fan even had his shirt vandalised by a visiting supporter while he was sleeping.

The Ajax fan drew an Amsterdam coat of arms on his Spurs shirt and turned the AIA sponsors logo into Ajax.

The police are reportedly on high alert, according to The Sun, as Ajax fans have a reputation for causing trouble at big games.

Before their quarter-final with Juventus, 54 Ultras were arrested before kick-off and were found in possession of knuckle-dusters, mouth guards and pyrotechnics.

The supporters all appear to be in good spirit in London, though, ahead of the first leg at the new Tottenham Hotspur Stadium.
