On Wednesday night, Atletico and Arsenal played out a 1-1 draw in the first-leg of their Champions League semifinal, with both teams converting penalties.
Sutton told BBC Sport afterwards: "People can talk about the Arsenal performance. Were they good enough in the final third? Probably not.
"I thought Atleti were excellent in the second half and deserved something from the game.
"Having said all that, there were two shocking decisions which went against Arsenal.
"I didn't think it was a handball by Ben White because the ball deflected off his shin first and his arm is out a little bit but the fact is it came off his shin first.
"And Hancko, clumsy as you like, steps on part of Eze's foot and they don't really protest - I always think that's the biggest tell from players. They did for the Gyokeres penalty really vehemently, got in the referee's face.
"When you see the referee go to the monitor you know what's going to happen, but I would have liked to see the referee be stronger in that moment. He gave it in real time and from everything I see from the monitor there was contact on Eze's foot. The penalty should have been awarded and Arsenal should be going back to the Emirates in a much stronger position."
