Clinton N’Jie has returned to full training ahead of Tottenham’s clash against Manchester United on Sunday, the club have confirmed.

The Cameroon international was pictured taking part in a group session with the first-team squad on Tuesday morning.

Spurs confirmed via their official Twitter account that N’jie was also set to take part in a second session later in the day.

The impending return of the 22-year-old winger could give Mauricio Pochettino a valuable extra option in the team’s title run-in.

Spurs are second in the Premier League ahead of Sunday’s home clash against United although they slipped seven points behind leaders Leicester in the wake of their 1-1 draw at Liverpool last Saturday.

N’jie has been out for four months after undergoing surgery on the his medial collateral ligament (MCL) in his right knee in December.

It has been a frustrating debut campaign in north London for N’jie, who signed from Lyon last summer in a £10.5million deal.

He has not played since the Europa League group stage victory at home to Monaco on December 10 and has played just 361 minutes all season.

In other Tottenham team news, vice-captain and defensive kingpin Jan Vertonghen is closing on a return to the team after a knee injury of his own.
