Things turned ugly during Celtic's friendly meeting with Ajax, as both sets of supporters clashed inside the stadium. The two clubs were competing in a pre-season tournament in Como when unsavoury scenes erupted between the fans in the terraces.

A sizeable Ajax contingent is said to have made the journey to Northern Italy, with Celtic fans having also turned up in strong numbers. However, as the sun set on the picturesque Stadio Giuseppe Sinigaglia, tensions boiled over in the stands.

Social media footage captured depicts fans from the two clubs banging on the perspex glass separating the sections, with security officials forced to intervene. Plastic pint pots filled with liquid can also be seen being thrown by both sets of fans, with some Celtic supporters also spotted waving Palestine flags.

On the pitch, Ajax blew Celtic away, with the Dutch outfit running out comfortable 5-1 winners. Steven Berghuis opened the scoring for Ajax, but Yang Hyun-Jun quickly fired back for the Scottish side to level things up.

It remained that way at the break, but Ajax put their foot on the gas in the second half and ran away with the contest. Goals from Davy Klaassen, Aaron Bouwman and Davy Klaassen, plus another via Berghuis confirmed Ajax's progression into Sunday's final, where they'll take on FC Como.

It comes just days after Celtic battered Newcastle United in an exhibition match, with the Ajax hammering somewhat of a reality check for the Scottish Premiership outfit. Speaking post-match, manager Brendan Rodgers urged the Celtic board to increase their investment in the squad ahead of the new season.

Rodgers said: “Yes, it depends what your ambition is. If your ambition is to really progress and push forward, then we need to improve the squad. But I can't fault the players. The players that are here, they've been working so well, so hard and you see some of the play and how they work has been very, very good.

"However, if you want to progress, then, as I said, you need to bring in quality and that's something that we hopefully can do... I think the scoreline didn’t quite reflect the game. I think that the first 60 minutes we played a lot of really good football with physicality, we broke through their pressure, scored one, could have had more."
