I don't think he's ready for Arsenal tbh, but it seems like both you and Spurs are really interested, just afraid he will end up on the bench. But also doubt we will even sell him next season if we get into Champions League, the offer would at least have to be a good bit higher than you usually pay smaller teams like Copenhagen.
Also worth noticing is that while he has been outstanding for us this season, it's also the very first time we actually see him on this level, last season he played about 30 min in one match and that was all, so will be interesting to see if he can keep it up. But as he is playing right now he's beasting everywhere and everyone seems to be real happy we finally got an alternative the Bendtner on the national team, but we haven't seen him have a down period yet and haven't really seen him play in many other systems than a 4-4-2 that we insist on, he can beat players on his own and he will win a lot of headers for you, but honestly it's hard as fuck to tell if he will fit Arsenal as we sure as fuck aren't playing like you, the few matches he has had for the national team he seems to do well in too though who plays closer to your style, or at least attempts to.
