Olympiakos leave behind a blurred performance in the Europa League and they are ready for a derby response against Panathinaikos on Sunday.
Pereira told his players to give their best for a derby win which will clinch the Super League title.
“You know that we didn't produce a decent display in Ukraine. We didn't stick to our plans and we suffered our first defeat. This can't change now. We don't have to think about Dnipro. We've got a big derby ahead. I want to see a brave performance against Panathinaikos. We have to stand up because it is a very important game. I want to see passion in order to get the victory. It's a derby, therefore you have to be concentrated. It's a must-win game, so I want to see you giving everything,” Pereira said.
