Manchester United defender Nemanja Vidic sat out training on Tuesday night, but should be fit enough to play in the Champions League semi-final first leg against Barcelona.

The Serb stopper only returned to the side from a spell on the sidelines with a knee injury in the weekend's 1-1 draw with Blackburn.

Wayne Rooney has recovered from a side injury sustained during Saturday's 1-1 against Blackburn after colliding with Ryan Nelsen but Sir Alex Ferguson said he is back at full fitness.

Rooney is expected to play as a lone striker, supported by the roaming Cristiano Ronaldo, with Carlos Tevez restricted to a place on the bench despite his goalscoring performance in the quarter-final second leg against Roma.

Edwin van der Sar is back in the squad following his groin injury and should take over from Tomasz Kuszczak, while Owen Hargreaves could also return after shrugging off a hamstring problem.

Sir Alex Ferguson has an embarrassment of riches in central midfield, and will have to perm three from Hargreaves, Michael Carrick, Paul Scholes and Anderson.

With captain Gary Neville also flying to Spain, United have a fully fit squad except for Louis Saha, whose absence will barely register given his dreadful injury record.

Barcelona boss Frank Rijkaard is expected to take a risk by starting star man Lionel Messi, who returned from injury in a cameo performance against Espanyol on Saturday.

Thierry Henry has come in for heavy criticism following a long spell of lacklustre form and trained by himself on Tuesday. The Frenchman is unlikely to return to the left wing to play a side against whom he had a fine scoring record for Arsenal.

Teenage starlet Bojan Krkic could deputise, while Samuel Eto'o is a near-certainty to start as a lone striker.

Yaya Toure anchors the midfield with Xavi, Andres Iniesta and Deco battling it out for central midfield places - the latter two players also returning from injury.

Captain Carles Puyol misses the game through suspension, meaning Rafael Marquez partners Gabriel Milito at centre-back. Sylvinho and Gianluca Zambrotta fill the full-back positions with Victor Valdes in goal.
