Dele Alli also joined Everton on a free transfer while Bryan Gil moved to Valencia.

"What happened in January was not easy," Conte told Sky Sport Italia.

Spurs boss Conte added: "We lost four players. Four important players for Tottenham and we brought in only two.

"So even just in terms of numbers, rather than reinforce the squad, we, on paper, may have weakened it."

Conte took charge of Tottenham on 2 November and oversaw a nine-game unbeaten run in the Premier League.

However, their form has faltered in recent weeks and three consecutive league defeats has seen Spurs drop to eighth, seven points off the Champions League spots - albeit with three games in hand on fourth-placed Manchester United.

Conte does not believe he was backed with ready-made signings in January and says he now realises the club's vision is to develop players.

The Italian added: "Bentancur and Kulusevski are ideal prospects for Tottenham, because Tottenham are seeking young players they can develop and grow, not players who are ready. That is the issue.

"This is the vision and the philosophy of the club. It is inevitable that, if you want to grow quicker and if you want to be competitive more rapidly, you need players with a lot of experience, because they also raise the experience level of the overall team.

"But I repeat, I have realised now that this is the vision of the club."
