Tottenham were undone by a former Arsenal academy player, so could Arsenal find themselves in the same situation at the Emirates?
Serge Gnabry scored four goals for Bayern Munich at White Hart Lane and Paul-José Mpoku will be aiming to shoot down the Gunners when Standard Liege visit in the Europa League.
Mpoku left Liege to join Spurs’ academy in June 2008, but never played for the club and was sent on loan to Leyton Orient before returning to the Belgium club in 2011.
He has faced Arsenal before when Orient were beaten 5-0 by the Premier League side and still calls London his ‘second home’.
A strong performance against Vitoria de Guimaraes in their first group game saw him score in the 2-0 win, while the midfielder has two league goals to his name so far in seven games.
After a loan spell at West Brom under Tony Pulis, Gnabry returned to Germany and after spells at Werder Bremen and Hoffenheim, has cemented his place in Bayern’s first team – and Spurs fans know what happened next.
Winger Maxime Lestienne said: “We will try to play football without fear. Nothing is impossible, is it? We have the qualities to try to pick something up. ”
The visiting supporters, meanwhile, have been making their presence in north London known, forcing King’s Cross tube station to close, though it has since re-opened.
