Arsenal striker Danny Welbeck will remain in hospital after suffering a severe injury to his right ankle in Thursday's game at Sporting Lisbon in the Europa League, the club said in a statement on its website Friday. "Danny will remain in hospital for treatment and will be under surveillance. Welbeck came out on a stretcher in the first half of the Group B match with a 0-0 draw, but the draw was enough for his team to qualify for the next round. The 27-year-old was injured when he fell wrong after a vertical attempt at Sporting, and his ankle seemed to have turned completely backward. The Spanish coach told Arsenal onay Emery after the match that Welbeck's injury had shocked everyone in the team. "When you play football, when you play at this level, things like that may happen, we do not wish that, but that's part of our profession." We think injury is serious. "Some analysts expect Welbeck to be out for months and will definitely miss both games. England will face the United States this month against the United States on 15 November before Croatia face the European League four days later. The Three Lions are second in Group Four in the League's first level, four points behind Leading Spain (6), and in front of the World Champions League Croatia (no One). .
