Former Tottenham and Arsenal defender Sol Campbell has questioned Spurs' title credentials

Former Tottenham defender Sol Campbell says a lack of 'winners' at the club could cost them their Premier League title bid.

Campbell made more than 200 appearances for Spurs before joining north London rivals Arsenal in 2001, with whom he won two Premier League titles.

He believes Mauricio Pochettino's side do not have the experience to see them through a tough run-in to become champions.

"Tottenham have been very impressive of late, but I think the same can be said of Spurs as that of Leicester - experience under pressure could be key to success," Campbell said in his latest Sportlobster blog.

"The last eight to 10 games of the season are when you really find out who you are as a player, team and a club as a whole.

"At the moment they are going along fantastically well and you have to say they have given themselves a chance of winning the Premier League, but they don't have a lot of winners in their team.

"By that I mean they don't have players who have experienced success in a league of this quality."

Tottenham leapfrogged Arsenal into third place on Tuesday following an impressive 3-0 win at Norwich - while the Gunners failed to breach a resolute Southampton in a 0-0 draw at the Emirates.

Spurs now sit five points behind leaders Leicester, but Campbell is unsure as to whether they have the enough experience to close the gap.

"They are a young side with a lot of talent, but they might lack a player who has 'been there, done that', the sort of player who will keep everyone calm, focused and believing that anything is possible.

"Leicester are in the same position - as a club they have entered unknown territory and it's going to be brilliant to see if either club can hold their nerve and produce a real challenge right to the end of the season."

Dele Alli is a 'real prospect', according to Sol Campbell

The former England international also sounded a note of caution about 19-year-old Tottenham midfielder Dele Alli, who earned a call-up to the national senior squad ahead of Euro 2016 on the back of impressive performances for Pochettino.

"He does look a real prospect, but it is very early stages for him," said Campbell. "I don't really want to know about a player until five or six years down the line and I can see their consistency.

"Anyone can have a good season or two - I want to see five, 10, 15 years of quality from a player to be able to call him 'world class'.

"We have seen players light up this league before for two or three years and then drop off and fade away."
