The fiery exchange between Messi and Paredes: Should Scaloni be worried?

There was a moment during Paris Saint-Germain's 4-1 victory over Barcelona which may have concerned Argentina head coach Lionel Scaloni.

Two of his Albiceleste players, Lionel Messi and Leandro Paredes, appeared to have a rather heated disagreement on the pitch, and the national team boss will be hoping any ill feeling between them stayed on the pitch.

Paredes made a couple of heavy challenges on his compatriot throughout the game and at one moment the pair could be seen arguing, with Messi giving him a less than impressed look as he appeared to accuse Paredes of complaining too much to the referee.

For Scaloni, Paredes is one of his favourites and an ever-present, while Messi's value to Argentina needs no explaining.
