Danny Welbeck and David Ospina to miss Arsenal's Everton visit
Arsenal's Danny Welbeck and David Ospina will both be out until the next international break but Laurent Koscielny should be fit to face Everton on Sunday, manager Arsene Wenger has said.
Welbeck and Koscielny limped off during the defeat at Watford on Sunday, while Ospina missed Thursday's Europa League win over Red Star Belgrade.
While Alexis Sanchez and Aaron Ramsey are ready to return after being rested against Watford, Wenger told Arsenal's official website: "Welbeck is out. He has a groin problem, and I think it will be two to three weeks before he is back.
"He will not be back before the international break.
"Mustafi will not be back before the break, and Ospina as well. Ospina is not very bad, he has a grade one [groin problem] so it's just a couple of weeks. Mustafi is a bit worse than Ospina."
Sanchez and Ramsey, like most regular starters, sat out the Europa League trip but "will be alright" to face Everton, Wenger said.
Arsenal are looking to secure their first Premier League away win of the season at Goodison Park, having lost at Stoke, Liverpool and Watford and drawn at Chelsea.
