Barcelona coach Xavi hailed the performance of Ilkay Gundogan last night.
The midfielder was named UEFA's man of the match for their Champions League win at Porto.
Xavi said: "We're lucky that we have him, he gives us the break, he's the one who turns, the one who divides, the one who breaks lines, he doesn't lose balls... it's a privilege.
"The rest shouldn't lose so many balls. We lacked patience and calm in opposite field.
"The players were happy. It is the most difficult club in the world, you win 1-0 and the glass is half empty. This is the Champions League. We won and everything seems little."
