We brought in a non mobile unproven in PL player at age of 35 called Ibrahimovic and he was awesome. Anyway theres always that myopic PL angle of can player x cut it in the PL. Class is permanent.
Cavani is 33, he's still quick for his age, likes to break the offside trap which will suit us and ole style of play. He can play off the wings as a wide forward as he did at psg when swapping positions with Mbappe and Neymar. Hes vastly experienced player which can only help our young forwards; rashford, martial and greenwood. Hes a winner, top pro who looks after himself physically and a strong personality, which we need in the dressing room.
His wages are inside our current wage structure. Hes better than ighalo by a huge margin. I have no issue with bringing experienced players in, fergie did that with blanc, larsson etc. Ole wanted a forward so i think this is his call.
