The Greek champions sealed a memorable win against an abject Red Devils side on Tuesday but their coach insists his side must fight to "make history" at Old Trafford
The Greek champions secured a fully deserved win in Athens on Tuesday thanks to goals from Alejandro Dominguez and Joel Campbell to put them in full control of their last-16 tie against the reigning Premier League titleholders.
Michel admits that the win was a momentous moment for both Olympiakos and Greek football as a whole, but insists his side must approach the second leg with the same sense of adventure in order to progress to the quarters.
"To beat a great side like United in the manner we beat them is very special. I can't hide my joy. I feel proud of my players. It was a great moment for us," he told Uefa.com after the match.
"But we must look ahead to the second leg. We still have the match at Old Trafford. We expect a different United at Old Trafford, we have huge respect for them.
"Anyone who thinks 2-0 is enough to qualify is mistaken: 2-0 is not enough to get through against United at Old Trafford. We have to keep on working to make it through and make history.
"Our team is becoming more and more of a team as time goes on. We were preparing for this game for a long time in silence.
"We picked the best moment to show that Greek football is alive and kicking. And that Olympiakos can take on great sides like United.
"[Wayne] Rooney and [Robin] van Persie are great players and we are glad we beat them today. But the second leg is still to come."
