Jose Mourinho reckons a change of fortune could help Tottenham find their way out of their current slump.
Sunday's 2-1 defeat at West Ham was their fifth in the last six Premier League games and severely dented hopes of a top-four finish, with the fourth-placed Hammers now nine points ahead of Spurs.
Tottenham appear a shadow of the side that topped the table in mid-December and Mourinho is in one of the worst spells of his long managerial career.
He said: "Jesse is a really talented footballer. It wasn't long ago that he was an England international who was making a big contribution. I think he can play in two or three positions and he has shown he has got a goal in him.
"Going into the January transfer window is never an easy time and I think this was probably one of the hardest because of the pandemic and the difficulty in getting players.
"So to bring somebody in who helps your team and improves it is not an easy thing to go and Jesse is improving it and making us better."
