Star striker, Diego Costa and Brazilian team-mate, Oscar were involved in angry clash at Chelsea's Cobham training ground as team-mates separate the attacking duo.
Chelsea stars, Diego Costa and Oscar were reportedly involved in an angry training ground confrontation on Thursday afternoon. The attacking pair had to be restrained after squaring up to each following a sequence of two hefty tackles during an intense training session.
The Brazillian is understood to have rattled Costa with a hefty tackle before the Spain international responded with hard-hitting tackle of his own.
The second clash is understood to have sparked the heated confrontation between the pair, who had to be pulled apart and were separated before any punches were thrown.
The clash is said to have de-escalated quickly with the pair said to have resolved their differences with each other at the end of the training session.
Following reports, Oscar hit out on Twitter on Thursday night denying the incident: 'For those who are talking to me and @diegocosta struggle today in training he's lying, he's one of my best friends and never fight.'
Regardless, the encounter will come as an unwanted headache for the club ahead of the FA Cup tie against Scunthorpe this weekend.
