Jermain Defoe believes that Tottenham could suffer due to their midweek game in the Champions League.

Spurs began their European campaign with a disappointing 2-1 defeat against Monaco on Wednesday and have had just three days rest before Sunday’s fixture against Sunderland.

The Black Cats travel to White Hart Lane in desperate need of points after one draw and three defeats from their opening four league games.

Former Spurs striker Defoe believes that his current team have a chance of causing an upset due to the European commitments of Mauricio Pochettino’s side, as quoted by Sunderland’s official website.

“It’s going to be difficult but I watched Spurs on Wednesday and they’ve not reached the levels they were at last year,” he said. “But its still early days and it’s the same with us so hopefully we can go there and be disciplined.

“As I said they played on Wednesday so maybe fatigue will kick in at the end of the game so we will just see what happens.”

Defoe represents Sunderland’s best threat in front of goal and they will hope to capitalise on his experience.

The 55-capped England striker has already notched up two goals in the club’s opening four matches and scored an impressive 18 goals in all competitions last season as the club avoided relegation.

He also enjoyed two spells at Spurs during the earlier stages of his career, scoring a combined total of 138 goals in 357 club appearances.

Pochettino’s side recorded a convincing 4-0 win over Stoke in their last league outing and will hope to redeem themselves for the Monaco defeat.

Spurs have begun their league campaign in good form and are one of only three clubs who are still unbeaten, with Manchester City and Everton topping the table after impressive starts.
