Tottenham maintained their unbeaten start to the season with a 1-1 draw against Leicester, but missed the chance to win after a Victor Wanyama error.

Spurs took the lead at White Hart Lane after Vincent Janssen won and converted a penalty shortly before the break, the Dutchman’s first goal in the Premier League.

However, champions Leicester found an equaliser early in the second half, when Jamie Vardy took advantage of Kenyan midfielder Wanyama’s poor header to set up Ahmed Musa.

The draw means Spurs are still undefeated in the Premier League this season, are without a win any of their last five games in all competitions.

Dele Alli forged the first clear-cut chance of the afternoon, when his stinging shot from 20 yards forced a save from Leicester keeper Kasper Schmeichel on 12 minutes.

Christian Eriksen was next to go close for the home side five minutes later, when his curling free kick from the left hand edge of the box hit the side netting.

The champions struggled to get a foothold in the game during the early stages, but a good cross from Riyad Mahrez on the half-hour mark was headed narrowly over by Shinji Okazaki.

Spurs almost took the lead on 40 minutes, when Alli’s first-time shot rattled back off the crossbar.

Kyle Walker did well to bring down a cross-field ball before crossing to Alli, who saw his effort hit the woodwork.

Three minutes later, Spurs were ahead. When referee Robert Madley pointed to the spot after Leicester centre back Robert Huth clumsily brought down Vincent Janssen.

Janssen himself stepped up to take the penalty, calmly slotting past Schmeichel to chalk up his first-ever goal in the Premier League.

However, just two minutes after the break, the champions were level again.

Wanyama’s attempted header back to his own keeper was pounced on by Jamie Vardy, who squared the ball to give Nigerian forward Musa the easiest of finishes.

Spurs reacted well to being pegged back and created a string of chances shortly after the equaliser, the best of which fell once again to Janssen.

Tottenham’s number nine almost had his second goal of the afternoon on the 70 minute mark, when his left-footed free kick from the right hand side fizzed narrowly over Leicester’s net.

Spurs hit the woodwork for a second time late on, when Jan Vertonghen’s header from a Wanyama cross cannoned back off the frame of the goal.

Tottenham, who have now drawn their last three league games, will look to get back to winning ways at Wembley, when they face Bayer Leverkusen in the Champions League midweek.
