Jeff Reine-Adelaide and Matt Macey were some of the lesser-known Arsenal players in training.
There was plenty of youth on display at London Colney this morning as Arsenal gear up for arguably their biggest match of the season ahead of facing Spurs in tomorrow's North London derby.
Rocked by the news that Petr Cech could miss up to four weeks, they will turn to David Ospina to deputise, and the Colombian goalkeeper was pictured with 21-year-old Matt Macey, the third-choice stopper who is expected to be named on the bench at White Hart Lane.
Also in attendance was highly-rated 18-year-old midfielder Jeff Reine-Adelaide, who made his senior debut in the FA Cup win over Sunderland back in January, but is unlikely to play a role tomorrow.
Twenty-year-old Serge Gnabry was pictured again following his disastrous loan spell at West Brom, which was cut short by the Baggies in January, while teenage sensation Alex Iwobi, 19, was also present.
