Dimitar Berbatov believes Tottenham Hotspur will be lurking in the shadows in the Premier League title race under Jose Mourinho.
Spurs sit in fifth place, seven points behind leaders Manchester United but with a game in hand.
Mourinho's men have lost just three matches in their previous 30 games in all competitions.
The Premier League has thrown up plenty of unexpected results this season and on Thursday night Liverpool finally saw their long, unbeaten record at Anfield ended by Burnley.
Spurs face Jurgen Klopp's men next week, having returned to winning ways in the Premier League with a 3-1 victory at Sheffield United on Sunday, with Tanguy Ndombele round off the day with a wonderful lob from a tight angle.
"They did look good and that Ndombele goal was special," Berbatov told Betfair.
"Did he mean it? Haha. He is turning into a smart talent and integrating into the team.
"This has benefited the whole team and I'm sure Jose Mourinho is happy."
On Tottenham's title hopes, the Bulgarian added: "For me, they are still in the mix with Leicester and the others, it is tight at the top and it is interesting.
"The chase is going to be great to watch. They will be there in the shadows. There is not too much stress on them to be mentioned as contenders, but they will be playing better if they are not under pressure and could surprise people.
"In my opinion, I think the main teams need to keep an eye on each other. It's very tight up there and it will be so interesting as teams will keep losing, drawing and winning games.
"Honestly, it is going to be tight and a must watch until the very end. You talk about United, City and Liverpool but you cannot underestimate Leicester or Spurs."
