Barca fans booed and whistled the youngster after growing frustrated with his over-elaboration when in possession and Rijkaard said in his post-match media conference: "He is a professional and has to overcome these things.

"You can say many things, but what no one can deny is that he is always working to help his teammates.

"There are details and individual moments that surely can be discussed, but at least he always works for his teammates. That is the most important thing."
