AC Milan boss Gennaro Gattuso says they must keep hold of Suso.
The midfielder has been linked with a move away this month.
But Gattuso says: “He's working hard and well, he's hardly stopped.
“It annoys me because I want to keep Suso at all costs. He can be an added value.
"He combines quality and quantity, has very precise skills and makes important runs on and off the ball.
“He has stamina and a strong heart. We're talking about a top player who can improve even further."
