Manchester United are considering an approach in signing Bayern Munich forward Thomas Muller at the end of the season, according to the Mirror.

The 24-year-old has been in fine form for last season's treble winners and has been their key player over the past few years. He has scored 12 goals and managed 10 assists in 29 league appearances this season.

The Old Trafford outfit are without a permanent manager after they allowed David Moyes to leave the club last month. Ryan Giggs has taken over the role as interim manager for the remaining fixtures of this season as United are yet to appoint a successor to the former Everton boss.

Louis van Gaal is strongly rumoured to take over the managerial reins at Old Trafford. He is currently in charge of the Netherlands and has confirmed that he would be ending his time with the national team after their campaign in the summer World Cup.

The report claims Muller is unhappy at the Allianz Arena and is ready to leave his current employers to follow the Dutchman to United in the summer transfer window. The former Barcelona boss is believed to be keen on landing the German international and has made him the top priority signing.

Van Gaal handed Muller his debut for Bayern's first team in 2009 while he was in charge of the Bavarian club. The forward's club and country teammate Toni Kroos is also on United's radar and the duo could follow Van Gaal to Old Trafford if the latter becomes Moyes's successor.

Meanwhile, United midfielder Tom Cleverley has revealed the appointment of Giggs as the interim manager and being named in his first starting lineup has given a confidence boost. The England international started during the Red Devils's 4-0 victory over Norwich City.

"Yeah, I suppose a little bit. I've been a little bit low. It's been quite a tough season at times for myself but Giggsy has come straight in and had a couple of little words with me through the week," Cleverley told United's official website.

"I was happy to be in his first starting XI. Hopefully, I can build on that in the last three games and really build up my confidence and get my sharpness back."
