PREMIER League star Joey Barton today admitted attacking a former team mate in a training ground bust-up.

The troubled midfielder, who plays for Newcastle United, admitted one charge of assault occasioning actual bodily harm on Ousmane Dabo when they were playing colleagues at Manchester City.

It is the latest in a long line of brushes with the law for the 25-year-old, who was jailed for six months in May after admitting assault and affray in a Liverpool branch of McDonald's last year.

Barton will be sentenced tomorrow morning.
