Manchester United defender Chris Smalling admits the club's Argies are his hardest teammates.

The Red Devils defender also took the time to take a cheeky swipe at captain Wayne Rooney.

He told Sky Sports: "Who is the hardest? Sergio [Romero] and Marcos [Rojo].

"They've got that Argentinian switch on them, they're not all there.

"If something bad was to happen, you want them in your group.

"Wazza got knocked out by Phil Bardsley so that lowered his reputation a little."
