Depends which Özil we’re talking about: the one who, every now and then, is absolutely sublime; or the one who had just 29 touches and created 0 chances against Chelsea? If we can guarantee that we get the former most of the time, then yes, we absolutely need him, but how do we do that? How do we coax it out of him on a regular basis? What tact do we take? Flatter his ego? Sting his pride? Get him angry enough to want to prove a point? I’m really not sure how we go about this when he basically has tenure, and can just fold is arms and carry on trousering 1.5m a month regardless?
