Personally I would be pretty unhappy with Antoine Griezmann, from a purely footballing standpoint it just doesn't make any sense, 30 years old off the back of at very best two average seasons, added to the fact he has only ever played in Spain, its just not the kind of signing we make these days. Plus all the other baggage that comes with him as a person, we are one of the best clubs in the world we are extremely attractive, someone like Griezmann, honestly adds nothing either on or off the pitch, frankly if he is our option for a striker I would look to muddle through like we did last season.
You don't sign a player like this as a stopgap, its insane! the guys value was 105m two years ago he is on 550k a week reportedly lets say you half both...... what kind of resale value is there in a 32 year old? so you have basically drained funds for 2 years have little value to sell on AND you still need to sign a striker and either give a free transfer, offload(and how many clubs could afford even half of what he is on now), or keep on your books. Basically this is a rich mans version of Danny Mills and that's before you get into the fact he isn't a great person you really want around your club.
