The Belgium international feels Spurs boss Andre Villas-Boas has strengthened his squad enough this summer to secure Champions League football come the end of the 2013-14 season
Spurs claimed a narrow 1-0 victory over newly-promoted Crystal Palace at Selhurst Park on Sunday, after Roberto Soldado netted a debut goal from the penalty spot.

"They're all strong lads, Capoue, Paulinho, Roberto and Nacer," he told Sky Sports after the game.
"We have a very strong, big team and we want to play for the prizes and Champions League qualification.
"Next time we have to score more goals. They were playing long balls to Chamakh and Phillips. We knew we needed to make it 2-0 but we didn't."
Chadli, who secured a €8.2 million move from Twente last month, impressed on his debut and also acknowledged Spurs will need to score more goals in order to kill games off.
The Belgian added: "We had a lot of chances and we needed to kill the game earlier. We got the three points today and I enjoyed it.
"It's quick in Holland but I like the way we played here today. Too bad it was only 1-0."
Next up for Villas-Boas' side is a trip to Georgia on Thuirsday for the first leg of their Europa League play-off against Dinamo Tbilisi.
