Barcelona superstar Lionel Messi was less than pleased after Tuesday night's Champions League defeat against Manchester City and a story has emerged that there was a post-match tunnel tantrum from the Argentine after a an apparent bust-up with Mikel Arteta.
According to the Sun, Messi took exception to the City coach's celebrations - high-fiving players on the sideline which carried on as shouting and fist-pumping in the tunnel area.
It is claimed that Messi sternly told Arteta, who himself has ties to Barcelona after graduating from the esteemed La Masia academy in the 1990s, to "go and enjoy yourself in the dressing room," adding, "do not do this here".
Other reports have mentioned a larger 'melee', while it is widely thought that Sergio Aguero, Messi's friend and international colleague, had to step in to calm the situation down.
The Sun notes that there are claims that Messi shouted "come here and show your face, don't hide," in the direction of the City dressing room before the situation was diffused.
Yet City seem to have denied there was any particular altercation or provocation from Arteta.
"Manchester City and Mikel Arteta would like to make it clear that Mikel did nothing to provoke an incident with Lionel Messi," a brief statement published in the Sun's report read.
A report from the Daily Mirror claimed that Messi, who scored Barcelona's only goal of the night to break the 0-0 deadlock, had already been on the warpath at half-time as well. The 29-year-old is said to have confronted referee Viktor Kassai after being denied a penalty for a trip by Fernandinho.
