"Both were really good players and professionals," he told liverpoolfc.tv. "They showed at Liverpool that they have quality. Both were important for us in different games.
"Sinama scored against Olympiacos and Luis scored a lot of fantastic goals. We have good memories of both players.
"Sinama is a player with pace and ability and he also has a very good mentality. He could be a very good player for any team.
"Clearly they'll both try to impress and they have quality. Both can score goals and both can change games. They will be a real threat for us."
