It's been suggested after yesterday's defeat to Real Betis that Keylor will now be departing.
But Marcelo says: "Players come and go. Some have made history and continue to make history, but it didn't sound like a goodbye to me, just as a farewell to a very tough season. Keylor has a contract and that will be resolved."
On the reaction of the supporters, he added: "When you win everything is easier. Whistles are a way to try to motivate us. If i let my head go down every time I heard a whistle, I would not be who I am. It's a way to motivate myself and improve what I'm not doing. We must try to change and reverse the situation. One day they whistle and the next they applaud you."
