In the 2-0 win over Alaves, Bale was seen wearing his face mask over his eyes as he lay in his seat.
He looked similarly selfless days later in the 2-1 win over Granada, at one point using a roll of duct tape as a telescope while in the stands.
The star was also a peripheral figure in Real’s title celebrations with the La Liga trophy.
But he’s arguably Britain’s most successful export after four Champions Leagues since joining from Spurs in 2013 for a world record of £ 86million.
