Marseille will be playing with an under-strength attack against a depleted Manchester United in the first leg of the last 16 of the Champions League on Wednesday.
Marseille striker Andre-Pierre Gignac is out for two weeks with a groin injury, while forwards Loic Remy (heel) and Brandao (ankle) are trying to recover in time.
"They trained normally today. I hope there won't be any further complications between now and tomorrow," Marseille coach Didier Deschamps said on Tuesday.
Also, France winger Mathieu Valbuena is trying to make it back to action less than a month after partially tearing his knee ligaments and damaging his ankle in a training accident.
"I won't take any risks with him given the matches we have coming up," Deschamps said.
United is missing center half Rio Ferdinand, veteran winger Ryan Giggs and Brazilian midfielder Anderson, although manager Alex Ferguson was boosted by the news that fullback twins Rafael and Fabio are both available.
Valbuena has been Marseille's best player this season and he resumed light training on Sunday, but Deschamps must decide whether to risk him at Stade Velodrome or wait until the return leg at Old Trafford against one of the top teams in the competition.
"Manchester starts the competition at the same level as Real Madrid, Barcelona, Inter (Milan), AC Milan or Bayern (Munich). There are six or seven teams who have the objective of winning the Champions League," Deschamps said. "They don't always get there, but Manchester regularly reaches the last four."
Deschamps, who regularly came up against United when he played for Juventus, expects a tight match.
"They have great talent in attack but they also defend very, very well. I don't think there will be a lot of goals," Deschamps said. "Knowing how important away goals are, we know it's vital we don't concede."
Keeping a clean sheet will be even harder because Deschamps also has problems in defense. Right back Rod Fanni and center back Stephane M'Bia are both nursing sore hamstrings.
Gignac's injury comes as he was starting to hit form after a terrible start following his offseason move from Toulouse. Gignac scored one goal in his first 10 matches, but managed five in the last six and set up Lucho Gonzalez for the opening goal against Saint-Etienne in last Saturday's 2-1 win.
With Gignac out, even more depends on Gonzalez, who has failed to match the form he showed helping Marseille win the league title last season.
United's 1-0 win over non-league team Crawley in the FA Cup last weekend has not dimmed Gonzalez's view of the Red Devils.
"We will pay a high price for every mistake," Gonzalez said. "They've got great players but there's nothing to say there won't be an upset. We saw that when Shakhtar Donetsk won in Rome."
Ferguson must decide whether to play strikers Wayne Rooney and Dimitar Berbatov together, or play a lone striker.
Deschamps will be likely to stick with one center forward - possibly Brandao or Remy - with Gonzalez playing just behind and two wingers.
"They are going to be confident of beating us, there is no doubt about that," Manchester United left back Patrice Evra said.
Evra reached the Champions League final with Monaco in 2004, when Deschamps was his coach.
"You can see they are a good team and they have a great manager," Evra said. "He is not afraid of any team, and I know he will get his players motivated."
Evra and Serbia center half Nemanja Vidic have been rare mainstays in United's injury-hit defense this season.
Ferdinand has not played since injuring a calf before United's loss at Wolves on Feb. 5, and fellow central defender Jonny Evans will also miss Wednesday's match because of a persistent ankle problem.
Chris Smalling was in line to start alongside Vidic.
Also, veteran striker Michael Owen is sidelined with a groin injury, while Anderson hurt his knee against Crawley.
