Lionel Messi involved in a heated bust-up with Ernesto Valverde after Barcelona was eliminated in the Champions League by AS Roma.

Los Blaugranas dropped a three-goal lead against Serie A outfit at the Stadio Olimpico last Tuesday with the La Liga side winning the first-leg 4-1 in Camp Nou a weeks ago but Roma secures a spot in the semi-final and dumped out Barcelona on away goal rule as the Argentinean could not believe his eyes.

Messi has pointed out as one of the angriest members of Barcelona's expedition to Rome, and he directed his sights to none other than his coach, Valverde.

According to reports by Spanish TV Show El Chiringuito, backed up by Catalan newspaper Sport, the 30-year-old had strong words towards his boss after Barcelona's particular Waterloo against Roma, questioning his methods and his inability to change the game's tide when things got tough.

Messi left the pitch without shaking anyone's hand on his way to the dressing room, where he allegedly waited for his team-mates and coach to vent his frustration.

So far, Messi and Valverde barely had any disagreements, but Messi's puns against the coach could be a sign of things to come for the Blaugrana side.

With reports stating that Gerard Pique joins in criticizing Valverde's tactics and approach that cause them exit from the Champions League in spectacular fashion.

Barcelona hope of winning the treble is finally dashed as they will now focus on winning the La Liga and the Copa Del Rey but it remains to be seen how Messi's words echo inside the club locker room, or if they have any effect on his coach's future.
