Team news: Defenders Wes Brown and Nemanja Vidic are doubts for Manchester United's Champions League clash with Roma at Old Trafford tomorrow.
The pair picked up knocks at Birmingham on Saturday and manager Alex Ferguson confirmed the two players were concerns.
Owen Hargreaves trained this morning, however, and is in line to make his European debut for United. Goalkeeper Edwin van der Sar (toe) is definitely ruled out, so Tomasz Kuczszak will deputise.
Elsewhere, Alexander Hleb will travel with the Arsenal squad to Romania for their clash against Steaua Bucharest after recovering quicker than expected from a knee injury.
The Belarus midfielder faces a late fitness test after being stretchered off at West Ham, along with striker Emmanuel Adebayor, who has a thigh problem.
Abou Diaby (ankle) and Mathieu Flamini (groin) are both also carrying knocks from the 1-0 win at Upton Park on Saturday, which kept the Gunners top of the Premier League.
Goalkeeper Jens Lehmann (elbow), captain William Gallas (groin), Tomas Rosicky (hamstring), Eduardo (groin) and Alex Song (calf) are all out.
Provisional Man Utd squad: Kuczszak, Heaton, Brown, Ferdinand, Vidic, Evra, Simpson, Pique, Ronaldo, Carrick, Scholes, Hargreaves, O'Shea, Anderson, Nani, Giggs, Rooney, Saha, Tevez.
Provisional Arsenal squad: Almunia, Sagna, Toure, Senderos, Clichy, Eboue, Fabregas, Flamini, Diaby, Adebayor, van Persie, Fabianski, Hleb, Denilson, Gilberto, Walcott, Bendtner, Traore.
