Malaga president Sheikh Abdullah Bin Nasser Al Thani said he will open an investigation into the manner in which his side lost to Borussia Dortmund on Tuesday night.
The Spaniards lost the Champions League quarter-final second leg in dramatic fashion when Dortmund scored twice in injury-time to win 3-2 at the Westfalenstadion.
The final goal was controversial as Felipe Santana appeared to be offside when he bundled the ball over the line in the 93rd minute prompting the Qatari billionaire to question whether or not it is above board.
"I'm sorry to go out this way injustice and racism," Al Thani posted on Twitter.
"I hope to open a thorough investigation UEFA regarding the Spanish club out this way.
"This is not football, but racism."
