Arsenal boss Arsene Wenger says the emergence of Jack Wilshere is proof he was right not to go out and sign a new midfielder this year.
He told the Daily Mail: "When Cesc Fabregas was a teenager, I would play him with Patrick Vieira and it did not work. Gilberto Silva and Vieira worked, Fabregas and Silva worked, but I could not play Fabregas and Vieira. But Fabregas was 19 and if he did not play I knew he would want to go, so we risked destroying everything, all the work we had put into this player. That is why I sold Vieira.
"Now we have that situation with Jack Wilshere. He is 17 and we cannot ask him to play every game to win the championship. But next year he will be ready, he will want to play all the time and if we have bought a player in his position he will want to go."
