The former Newcastle United attacker eventually signed for Tottenham on deadline day.
"I told him to favor Arsenal," said the centre-forward. "It was a rather special ending.
"Until the end, he did not know what he was going to do or what was best for him. It's been a long month for him so it's good that the ending is done, even in the last moments.
"It's great for him, Tottenham is a big stable club of our championship. Inevitably, we wanted him after a nice Euros to join a Premier League club. He will be a competitor for the title this year. I hope he will not be fit against us!"
