Arsene Wenger has admitted Laurent Koscielny is still not 100 per cent.
Arsenal manager Arsene Wenger has admitted defender Laurent Koscielny is still troubled by his injury.
The Frenchman made his first appearance since early October against West Brom at the weekend, helping the Gunners keep a clean sheet in a 1-0 win.
The club had struggled defensively with his absence, with his normally strong partnership with Per Mertesacker broken up.
Boss Arsene Wenger has revealed however that the Frenchman is not out of the woods yet, despite his return to action.
"Koscielny could be a problem because his inflammation of the achilles is not completely gone.
"He had two tendons which were bad. The left has gone completely and the right is still a little bit there so, if he has no reaction, he can cope with it. If he has a reaction, you have to be cautious."
Wenger's candidness is to be admired, but it will backfire if Koscielny suffers another setback.
It would also be a problem of his own creating, for his desperation to rush the Frenchman back to action is due to a lack of adequate cover.
He also confirmed yesterday that Nacho Monreal, who has deputised, is an injury uncertainty himself for the clash with Southampton, and could even be needed at left-back with Kieran Gibbs also missing training.
