Walcott is at the end of his career. Gerri is 23 and hasn't cut it at everton when he was 20. Or Milan and Barca. There is a lot of players who aren't good enough for barca yet go on to be brilliant players.
28 is peak career, not end of career.
Even tho i love Gerri, Walcott by the time he finishes would have scored more and assisted more in his career than Deolofeu.
in the league Walcott has 69 goals in 292 games. over all he has 113 goals in 422 appearances. Gerri aint getting anywhere near that.
