Tottenham Hotspur midfielder Dele Alli has calmed fears over the illness which forced him to be substituted at half time in the win over Norwich City. The 19-year-old was replaced by Nacer Chadli at the break after complaining of dizziness but is expected to be fit for the Premier League visit of Watford.

Alli had earlier set Spurs on their way to a comfortable victory at Carrow Road, with a goal inside two minutes as he reacted first to Declan Rudd parrying Christian Eriksen's shot. Sebastien Bassong then fouled Alli in the box, leading to referee Kevin Friend pointing to the penalty spot and Harry Kane converted to double the advantage.

Kane added a late third to see Tottenham leapfrog north London rivals Arsenal into third and keep pace with leaders Leicester City, who are five points ahead. Alli's withdrawal was however one of the main talking points after the game, but the former Milton Keynes Dons midfielder has reassured supporters he will make a full recovery.

"I was just a bit under the weather, feeling a bit dizzy so nothing too bad," the Tottenham youngster told the club's official website. "We knew they [Norwich] wouldn't make it easier for us. It is not an easy place to come but we had to focus on ourselves, focus on our aims and make sure we left with the three points in the end. We had a game plan and we knew if we stuck to it, the chances would come and we just had to finish them off.

"They weren't going to make it easy for us and after we got the goal we had to finish it off and thankfully we did that with the third goal. We like to work hard and we don't stop fighting until the end of the match and I think we showed that getting the goal late on and it was a comfortable win for us. I've still got a lot to learn, I am still only 19 and I can't think of a better place to do that."

Manager Mauricio Pochettino later confirmed that Alli would recover in time for Tottenham's next game against Watford on Saturday [6 February] and that the player was taken off following advice from the team doctor. "He was a little dizzy, he felt unwell and with advice from the doctor we took the decision to substitute him for Nacer Chadli," he said, according to the club's official website. "It's always better not to take a risk but now he feels much better. It's not a serious problem."
