William Gallas has revealed that his former Arsenal team-mate Philippe Senderos used to 'genuinely panic' before games and one of his main triggers was when he faced Didier Drogba.

Gallas, formerly of both Chelsea and Arsenal, has claimed that the Swiss defender severely struggled to compose himself before matches which then brought on abrupt and intense spells of fear in the dressing room.

In an interview with RMC Sport, Gallas said that Senderos would profusely sweat and panic before big games against the likes of Chelsea and their prolific target-man Drogba.

'I knew Philippe Senderos, before a match he would need to speak a lot, you could see that he was sweating, that he did not feel good,' he told Le Vestiaire.

'Especially against certain players. I saw him against Chelsea, against Didier Drogba, where he would genuinely panic, like he was going through his match before playing it.

'And unfortunately, when you saw him on the pitch, he lost his playing abilities, he didn't play well. But against his own team-mates, he played better.'

However, it wasn't just Senderos who had his own meltdowns at the club.

Gallas was prone to his own tantrums after he refused to leave the pitch after a 2-2 draw with Birmingham, during which former striker Eduardo horrifically broke his ankle.

Despite struggling mentally with some Premier League fixtures, Senderos managed to win an FA Cup and Community Shield during his seven years at the club.

The ex-Swiss international currently plays for MLS side Houston Dynamo and has won 57 caps for his country.
