Jurgen Klopp
Jurgen Klopp says the loss to Arsenal was 'damned unnecessary.'

Manchester United have reportedly earmarked Borussia Dormtmund manager Jurgen Klopp as David Moyes' replacement, should the current boss fails to secure Champions League football next season.

Moyes took charge of the Premier League holders last summer, after Sir Alex Ferguson's retirement, but he has struggled to make the impact expected. United are already out of both the FA Cup and Capital One Cup and while they qualified for the Champions League last 16 as group winners, their situation in the Premier League is far from good.

United are currently lying in seventh place, 15 points behind leaders Chelsea and 11 points from fourth place, which currently belongs to Liverpool.

Although Moyes signed a six year contract, Bild reports that United's officials have lost confidence in the manager and they have targeted Klopp as his replacement in case the Scot doesn't achieve a top-four finish.

Klopp, 46, has lately garnered a reputation as one of the best young managers in the world, not only because of his success at Borussia Dortmund but also for his atacking style of play.

Despite having to face the powerful Bayern Munich in the Bundesliga, Klopp managed to win the domestic league in 2010/11 and 2011/12, while last season he led his team to the Champions League final after beating Real Madrid in the semis.

The German manager was linked with Chelsea and City last summer, before they appointed Jose Mourinho and Manuel Pellegrini respectively. He recently admitted the two Premier League clubs were interested, but claimed he rejected their proposals because he wanted to stay at Dormund.

"There were some English clubs that called and wanted to speak with me But there was no reason to talk to them because... No chance," Klopp said.

"It's only hard to understand if you always think 'I can go to a bigger club'. I'm sure you could earn much more money at one or the other English clubs, or at a Chinese or Russian club. But it's not the most important thing."

However, the former Mainz manager may be tempted to move to Old Trafford next summer, especially considering that Bayern are likely to win the Bundesliga this season again and he is upset with Dortmund bosses after Robert Lewandowski confirmed that he is going to sign for the Bavarian giants this summer, just a year after Mario Gotze made the same choice.
