Lionel Messi's attitude has been heavily questioned by Joe Cole following Barcelona's humiliating 4-1 home defeat against Paris Saint-Germain on Tuesday.
Barcelona, who have been somewhat in a crisis in recent times both on and off the pitch, endured another low on Tuesday after they were all-but knocked out of the Champions League at the last-16 stage.
Messi had put Barca, currently in a state of financial turmoil, ahead in the first-leg from the penalty spot in the 27th minute but things turned ugly moments later as Kylian Mbappe scored a hat-trick while Moise Kean also netted for the French giants.
