The incident happened when the pair became entangled as they battled for the ball near the goal line with the score at 1-0 before Rudiger confronted a giggling Suarez about his cheeky pinch.
It wasn’t clear at first what had angered Rudiger, but replays showed Suarez had squeezed the inside of the Chelsea defender’s thigh.

Rudiger, clearly not impressed, had a few words for the Uruguayan as well as a push, and the pair squared up momentarily before being separated by the referee.
BT Sports pundits Joe Cole and Rio Ferdinand joked that Rudiger got off lightly given the forward’s checkered history of biting opponents.
‘When you’re telling your kids off, and they go from biting to pinching, you’re doing alright,’ joked former Blues midfielder Cole after the game.

Suarez was suspended for seven games in 2010 after biting PSV Eindhoven’s Otman Bakkal on the shoulder and got a 10-match suspension just three years later at Liverpool for biting Branislav Ivanovic’s arm.
Suarez clearly hadn’t learned his lesson by then with his 2014 World Cup campaign infamously remembered for a bite on Italy’s Giorgio Chiellini.
The 34-year-old has however never done it since then, but still enjoys a physical battle and getting underneath defenders’ skin anyway that he can.

‘He’s so, is cute the right word?’ Rio Ferdinand said about Suarez. ‘The referee is never going to see that, he’s looking at their faces, but the real damage is done down there somewhere. It’s like, street.’
Chelsea will nevertheless be delighted by their night’s work, having taken the advantage in the tie after Olivier Giroud’s spectacular overhead kick won them the game.
Although Suarez’s pinch was more petulant than an act of violent conduct, it remains to be seen how UEFA will receive it and if they will opt to take any retrospective action.
