Roma defender Kostas Manolas has spoken of clashing with Manchester United striker Zlatan Ibrahimovic.

Greece international Manolas claims the veteran striker is a real handful to play against.

“Ibra is a force of nature, you practically can't keep up with him during the match because he has an incredible physicality," he told Roma's official website.

Manolas also revealed the other toughest strikers he's faced - Barcelona hero Luis Suarez and Real Madrid ace Karim Benzema.

“I faced Suarez this year in the 2015-16 Champions League against Barcelona," Manolas added.

“He is someone who wants to score and who sees the goal. He is ferocious, tough to keep at bay and lethal in front of goal.

“Benzema is also a difficult opponent. He is complete, because he is physically strong and very technical.

“When physicality and quality come together it isn't easy to find the answer for us defenders."
