We would be handicapping ourselves hugely. It's not impossible to win the league but we would be heavily reliant on a few players and would also need our rivals to have average seasons as we would get nowhere near the points tallies of recent seasons.
Everybody screams Torres is a striker whenever he scores a goal, I don't disagree he looks much better there but if he was playing as a striker for another side, we wouldn't be looking at him. as an alternative, it makes sense but we have plenty of alternatives already in jesus, sterling and the kdb/bernardo/foden false 9. we need an undisputed number 1 striker and he's not an aguero replacement.
Delap hasn't yet played in a game where he isn't double the size of his opponent and can't just rely on bullying them yet, he won't be playing any meaningful minutes for us next season. Pep would play any senior midfielder as a false 9 before starting Delap in a big game.
