Johannesburg, Jan 06 : Current Premier League leaders Chelsea are monitoring the relationship between Argentina captain Lionel Messi and Barcelona coach Luis Enrique, which continues to worsen at the Catalan club.

A Spanish newspaper has reported that Messi is unhappy with coach Enrique's way of running the dressing room at Barca and in light of the same 2015 might prove to be the year Chelsea makes their move for the Argentine.

It has been revealed that the club's first training session of 2015 was marred by a war of words between the two when Enrique failed to award a free kick to Messi during a 5-a-side game, Sport24 reported.

Messi has reportedly grown irritated by the excessive authoritarianism of the coach, and this has left the situation between the coach and the club's star player on tenterhooks. (ANI)
