Arsenal, Man Utd to challenge Milan for Diego Costa

Premier League holders Chelsea may have to sell Diego Costa at a bargain price after the player revealed his rift with manager Antonio Conte.

The Spain international bagged 20 goals in the Premier League last term as the Blues cruised towards their fifth English title.

In spite of this, his relationship with Conte worsened midway through the campaign when the manager demanded him to leave the club following a bust-up in training.

Costa therein managed to retain his place in the starting lineup to become a key force in the Blues run-in to the title, but this has not ended the feud between the pair.

According to The Sun, both Manchester United and Arsenal are keepings on the Brazilian-born striker, who could be available for a fee of just £22m - £10m less than what the Blues paid to Atletico Madrid in 2014.

Earlier this week, Costa revealed his spat with the Italian head coach stating that he is no longer wanted at Stamford Bridge, and it appears that he is on the way out with AC Milan having already begun negotiations with his representative.

Atleti has remained Costa's preferred option after Chelsea, but the club's transfer ban restricts the striker from playing until January which could, in turn, affect his World Cup ambitions.

United boss Jose Mourinho worked alongside Costa for nearly 18 months at Stamford Bridge while Arsene Wenger has previously admitted that Costa was an option for the Gunners prior to his cross-city switch.
