After Quique Setien insisted that Lionel Messi was difficult to manage at FC Barcelona, it has now been claimed the pair had a huge dressing room spat once, and what they said to each other in that moment has now reportedly been revealed. 

'Messi Should've Been Sent Off For Kicking Ball At Referee'

Setien was replaced by Ronald Koeman following the Catalan club's 8-2 loss to0 Bayern Munich in last season's UEFA Champions League quarter-finals, but things for the Spanish tactician were reportedly tricky long before that result. 

In a recent interview, Setien claimed that the six-time Ballon d'Or winner was difficult to work with during his six months in charge, saying that "he's very reserved but he makes you see the things that he wants. He doesn't talk much."

Following the ex-Real Betis manager's remarks, new details have seemingly emerged over a dressing room clash between Messi and Setien after a 2-2 draw against Celta Vigo in June, a result that hurt Barcelona's chances of retaining the LaLiga trophy. 

Spanish outlet Mundo Deportivo reports that the 33-year-old had asked Setien to respect the players in the team who had won more than him, to which the former Barca boss is said to have replied: "If you don't like what I said, you know where the door is."

Setien was in charge of the Blaugrana for just 25 games, and claimed victory in 16 of those matches.
