He was heavily linked with a move away from the London club during the January transfer window but the Premier League side refused to let him leave.
It seems that his situation at the Premier League club is improving now.
Mourinho has revealed that he is happy with the attacking midfielder who is starting to show his true qualities.
It will be interesting to see if he can win over the Portuguese manager and hold down a regular starting berth at Tottenham now.
The Spurs boss said: “I’m happy with him. Difficult period. Sometimes small injuries in accumulation are more difficult than a big injury where after a few weeks or months you are back. Small injuries are mentally not good, players getting disappointed, lack of motivation, frustration. He went through all that. He came back. We had good conversations, training well, playing minutes or part of matches. Not yet a 90 minute match but he went through periods and basically now 75 or 80 minutes. Condition also improving. His feelings after matches always is better. For example in the first match in Budapest, he played 60 minutes or something like that and he super, super tired after the game. Now it is Sunday and then Zagreb and then Palace and then Zagreb and Arsenal and never stop so we need everybody and in the particular case of Dele Alli I’m very happy.”
Front four to play together?
Meanwhile, the Spurs boss also reflected on the option of using Dele Alli and Gareth Bale alongside Harry Kane and Son Heung-Min in a front four.
Mourinho has revealed that all four players are top-class players and if they are fit and ready to play, they should be able to play together.
It will be interesting to see if Tottenham can get their front four playing together in the coming weeks. It could improve them immensely in the final third and help them climb up the table.
Mourinho said: “When they are in top form, and when they are fit, and when they are ready to play matches, is never a problem for good players to play together.”
