Cape Town - Leicester City manager Craig Shakespeare says he has put last week's penalty injustice behind him as he focuses on overcoming Atletico Madrid at the King Power Stadium on Tuesday night.
A 28th minute Antoine Griezmann penalty secured a narrow 1-0 win for Atletico at the Estadio Vicente Calderon last week.
Referee Jonas Eriksson awarded a spot-kick for Atletico for a foul on Griezmann by Marc Albrighton, although the infringement clearly occurred outside the box.
Ahead of their second leg, the Foxes manager said he is fully focused on the game while admitting he is pinching himself at the thought of maybe making it to the Champions League semi-finals.
"No it's not gnawing away, the referee gave his decision and the last thing the club and players need is me harping on about it," said Shakespeare.
"We have to get on with it. The referee made his decision - although it's there for everyone to see it's the wrong one. We have to make sure we're ready and focused for the game."
"The focus just has to be on that game, you can look ahead and look back but you have to focus on the here and now.
"Where the club has come from is remarkable and if you had said last year 'you'd win the Premier League and this year be in the quarter-finals and with a chance to be in the semi-finals' everyone would have been pinching themselves."
Kick-off is at 20:45.
