Wigan boss Roberto Martinez has praised Manchester City as a potentially world-dominating team.
The former Wigan midfielder will lead his team to Eastlands tomorrow (Saturday), where he has admitted that the side face a huge challenge against City.
"That team is now near enough unplayable when they go forward. They were a joy to watch against Spurs," he said.
"It's as good as it gets in world football - never mind in the Premier League."
Wigan currently sit at eighth in the Premier League with five points.
