Tottenham defender Jan Vertonghen has praised Arsenal for their style of play - but says he doesn't believe they will be able to last the pace in the title race.
Arsenal currently sit top of the Premier League, five points clear of their nearest rivals Chelsea following their convincing 2-0 win over Liverpool on Saturday.
Spurs are in 4th having passed up the chance to close the gap on their rivals and move up in to second on their own with their 0-0 draw against Everton at Goodison Park on Sunday.
Both sides have been tipped to feature in the Premier League title run-in but it appears as though the Gunners are best equipped to do just that after their exceptional start - which includes a 1-0 win over Spurs.
While Vertonghen admits he has been impressed with Arsenal thus far, he believes they can only be called title contenders if they can keep up their recent good form.
"It's too early to call Arsenal the title contender," he told Belgian TV station Telenet.
"The only thing you can say is that they're stronger than last season. They have a stronger squad, can play different systems and have a great bunch of creativity in their midfield. Although I expect still a lot from Manchester City."
While Spurs have had their best ever start to a Premier League season that tells only half the story.
Although Andre Villas-Boas's side currently occupy a Champions League qualification spot they have managed just nine goals in 10 league games - just three more than bottom-placed Crystal Palace have scored.
"Defensively our team is strong," he continued. We had a clean sheet in 12 of 16 games. We only played one bad game: [the defeat] against West Ham."
Spurs have managed seven clean sheets in 10 games to earn the second best defensive record in the league.
Vertonghen has become a key part of Tottenham's defensive solidarity and showed his versatility when he put in a man of the match performance against Everton away from his usual central role at left-back.
"I can play left back, I'm helping the team out on that position," he said. "When there are some injuries, I'm the first back-up option.
"Sometimes it better to play on one position. If you look at other players, they just can focus on playing in their position and specialise in it."
