"We haven't taken a decision on Patrick yet," said PSV Eindhoven head coach Ronald Koeman.
"We'll first assess the situation and then see whether he'll get playing time. It is our duty to choose the most suitable time to do so. The Liverpool game would be an option, but we realise only too well that it's a top-level game.
"He needs playing time to get fully match fit. He is doing quite well. He has been training well the past nine days and was made to work really hard. Patrick is keen to show his abilities soon."
