Manchester City skipper Vincent Kompany has backed centre-back partner Eliaquim Mangala to come good amid rumours the defender could be loaned out.
Reports surfaced on Monday suggesting the Frenchman, who cost City an eye-watering £42 million, could head to Valencia for a season in exchange for sought-after Nicolas Otamendi.
City, though, have fervently denied such claims and Kompany believes Mangala just needs a little time to prove his worth in the Premier League.
"People always underestimate the hardship of this league," he said. "It is very rare, especially with a central defender, for someone to come in and dominate. It is very hard.
"Our defending against Chelsea was made easier by the fact we defended well as a team.
"We have a style of play where we play very high with a lot of space, so a lot of individual challenges are required.
"Because of that, it is only when the whole team works like we did that we get great defensive performances."
