Swansea striker Danny Graham has identified Tom Cleverley as a key threat ahead of Manchester United's visit to the Liberty Stadium this weekend.
The champions travel to Wales for the first time in the Barclays Premier League looking to close the gap on table toppers Manchester City with three points.
Swansea, though, will provide Sir Alex Ferguson's side as they look to maintain their unbeaten start to the season on home turf.
Graham is, however, well aware of the dangers United hold, and believes Cleverley will be integral to any success for the Red Devils on Saturday.
The United midfielder played with Graham during a loan stint at Watford, and the former Hornets hitman knows what to expect of 22-year-old Cleverley.
"United have bags of talent in every area of the pitch," Graham told the official Swans website.
"You look at Rooney, Nani, Hernandez, Valencia etc - all top players. But if you take your eye off someone like Tom Cleverley, then he will be very dangerous and clinical.
"I obviously know him very well from my Watford days - he made a big impact there and showed his quality.
"He scored a lot of goals in midfield and after that stint at Watford - and another at Wigan - he has settled into the United team and he's being mentioned with the England squad now too."
