Lucas Moura is the only player Tottenham have signed since the start of 2018, but Mauricio Pochettino does not expect deadline-day deals.

Mauricio Pochettino does not think there will be a signing at Tottenham on Thursday's transfer deadline day.

Spurs have only signed one player, Lucas Moura from Paris Saint-Germain, since the start of 2018.

Pochettino continues to keep Spurs in the top four despite the lack of additions to his squad, with Son Heung-min and Fernando Llorente striking late at a sparsely populated Wembley to earn a 2-1 comeback win over Watford on Wednesday.

With Harry Kane and Dele Alli both set to miss next month's last-16 Champions League clash with Borussia Dortmund due to injuries, attacking reinforcements would be welcome for Tottenham.

But Pochettino is downbeat about the chances of chairman Daniel Levy delivering a surprise signing to beat the deadline.

"No, I don't know anything," Pochettino told reporters when asked about rumours of Georges-Kevin N'Koudou moving to Monaco on loan.

"I am going to talk now with my chief scout Steve Hitchen, I am going to ask for some news. I expect that maybe some player is going to leave but I do not expect that we are going to add to the squad.

"I am going to talk because I want some news, but not because I am expecting to sign a player."

Son made an immediate impact by scoring the equaliser on his return from the Asian Cup, the South Korea captain available earlier than expected after his side lost in the last eight.

"I am always happy with him, he is a very nice guy and he is available always to deliver the job you expect from him," Pochettino added.

"It is so important to have all of the players fit and of course he was disappointed to lose the quarter-final against Qatar, he wanted to deliver his best for his country and win the Asian Cup but in the same time, I need to be honest, I am happy he is back because he is helping us to try and win and that is so important.

"It wasn't the plan to play with him for the full 90 minutes but how the result was, you know in that moment I talked with [assistant manager] Jesus [Perez] and I said maybe we need to take a little bit of a risk to keep him playing. He finished very tired, with some cramp.

"We're going to see if he can recover for the next game [against Newcastle United on Saturday], if he's okay maybe he's going to be in the starting XI, if not on the bench. For sure if we need him, he's going to help the team. That's one circumstance more."

Kane's replacement Llorente had missed a series of chances but the much-maligned forward came up with a late winner to down Watford, celebrating the goal with Pochettino.

"I don't think he wanted to come to me!" Pochettino joked. "I moved into his run, I put myself in the way to try to celebrate with him. I was so happy. Normally I never celebrate goals but today I felt a bit of freedom to celebrate because we deserved to win.

"For me this game was so important because before the three points was going to be massive and for me massive to keep our position in the table. Also so happy because Fernando worked so hard, working the last four games with Harry Kane out, he's working so hard for the team, to help the team to win three points today is a massive thing.

"Always it builds the confidence in a striker and more when you are competing with Harry Kane, or behind Harry Kane, one of the best strikers in the world, always it's difficult. Always you need time. But in all this time he's been a fantastic professional and always was pushing and helping the team."
