Barcelona substitute Gerard Pique was sent off at halftime of their win at Osasuna.

After seeing Robert Lewandowski dismissed in the first-half Pique, at the break, went to look for ref Jesus Gil Manzano on the field of play to ask him for explanations about his decisions -- a conversation that lasted until the referee entered the tunnel and beyond.

In the exchange of words, Pique was clearly not happy with the decisions made in the first half. His claims did go down well with the match referee, who ended up showing him the red.

In what would have been the last game of his career, Pique did not play a minute in the first half and was not able to come on for his 617th Barça appearance.

The referee's report later stated:

"Gerard was sent off for the following reason: Once the first half ended, inside the tunnel, he spoke to me in the following terms: "Have you seen the corner [for the Osasuna goal] you gave against us? You are the referee that has f***ed us the most by a distance.

'Other incidents: Once his dismissal had been communicated to the club delegate, he continued repeating the same expressions detailed above and had to be led into the dressing room by club staff, while he spoke to me in the following terms: 'You are a f***ing disgrace, go f*** yourself'."
