Leandro Trossard and Martin Odegaard both start for Arsenal in today’s Premier League meeting with Fulham.
Gabriel Jesus is also in the squad.
Manchester City’s win over Crystal Palace has cut their lead and the pressure is on.
Odegaard and Kieran Tierney were both ill during the week and missed Thursday’s 2-2 Europa League draw with Sporting in Lisbon. Trossard was also absent after injuring his groin against Bournemouth last weekend.
