Germany legend Mirsolav Klose has blasted Manchester United manager Louis van Gaal for giving him the hardest time of his career at Bayern Munich, Daily Star reports.

Klose left Bayern for Lazio in 2011 after failing to satisfy the current United boss, managing to score only 12 goals in 60 appearances for the Bavarians.

“It was a tough time, particularly working with Van Gaal,” Klose told German newspaper Die Zeit.

“I didn’t feel free. It was very difficult for me to fulfil his expectations. He was asking me to make runs I just couldn’t see.

“I gave it all I could, but sometimes it just wasn’t enough.”

The German World Cup record goal-scorer went on to praise his Lazio fans and national coach Joachim Löw for supporting him after his dreadful two years with Van Gaal.

“The support from the fans was always important for me,” he continued.

“We as footballers are meant to excite the fans, but for me it worked in the other direction. Maybe that is why I was able to play without any worries.”

Klose scored 41 goals in 101 games for the Serie A club, before winning the World Cup this summer and breaking Brazilian legend Ronaldo’s World Cup scoring record of 15 goals.
