Tottenham Hotspur have made an approach to sign Manchester United full back Alexander Buttner on loan until the end of the season with an option to buy the Dutchman this summer, reports suggest.

The former Vitesse Arnhem full back has failed to impose himself on the United first team following his move to Old Trafford 18 months ago and appeared to be on the brink of leaving the club during the summer.

Having failed to impress David Moyes this campaign Buttner's agent has indicated a temporary loan move could be on the cards given the defender's hopes of receiving a call up to the Dutch national team for next summer's World Cup.

Dutch newspaper De Telegraaf report Tottenham are keen bring the defender to White Hart Lane when the transfer window reopens next month with Tim Sherwood lacking cover on the left hand side of his defence.

While Danny Rose has returned to action from injury this month the Spurs boss is still lacking a natural option to provide back up, with neither Jan Vertonghen and Kyle Naughton comfortable in that position and youngster Zeki Fryers still largely unproven.

Although Buttner would still appear to be higher than Fabio da Silva in the pecking order at left back, he has still started just four games for United in all competitions this season. And given United's attempts to sign both Everton's Leighton Baines and Real Madrid's Fabio Coentrao last summer, it would appear David Moyes is still keen to add to his options whether or not Buttner is at the club or not.

A possible exit from Old Trafford was suggested earlier this month amid interest from Serie A duo Roma and Genoa. Buttner's agent Alexander Bursac later addressed such rumours, indicating his client was keen to secure a move with greater guarantees of first team football.

"He wants to play in the World Cup and needs more space. Genoa and Roma want to inform the club (Manchester United) of this interest. I hope they are willing to do it," Bursac said.
