Former teammates are all praying for Bolton Wanderers midfielder Fabrice Muamba after he collapsed during the FA Cup tie against Tottenham.

The London Chest Hospital later said Muamba was in a 'critically ill condition in intensive care'.

Spurs player Rafael van der Vaart was one of those visibly upset when Muamba collapsed and later took to Twitter to express his feelings.

"Terrible what happened with Muamba during the game," he said. "We're all praying for him."

England midfielder Jack Wilshere, who played alongside Muamba at Bolton, posted a message saying: "Hope Muamba is OK. Thoughts with him."

Middlesbrough defender Justin Hoyte, who played in the Arsenal youth team with Muamba, used Twitter to say: "I seriously hope my best friend in football is OK. Stay strong bro [sic], please please stay strong. God is with you remember that."
