You can see he’s a crucial player for Arsenal. He’s a top quality player and he brings quality to the pitch, for Arsenal and England.“I think he’s very important, as everyone can see.“Managing niggles going into a competition is very important for the latter stages.“You need important players like him to be ready to play and step up when called upon.”England will qualify for the knockout stages with victory over Ghana in Boston.
