Gerard Pique was sent off at half-time of his final match before retirement, seemingly for remonstrating with the referee, but Barcelona fought back to beat Osasuna 2-1 and move five points clear at the top of La Liga on Tuesday.
The 35-year-old Pique, who waved goodbye to the Camp Nou last weekend, was incensed by referee Jesus Gil Manzano's decision to show Barca striker Robert Lewandowski a second yellow card just after the half-hour mark.
