Barcelona coach Xavi is excited working with Robert Lewandowski.
The Pole again struck in the 3-0 win at Sevilla.
Xavi said, "It's not just goals, it's his work off the ball, how he presses, he is a spectacular reference for us. He is a fantastic player, his timing, the solutions he finds. It is all indicative of the maturity he has.
"He's helping us a lot, his leadership, the thing people don't see, he helps everyone, staff, youngsters, the veterans. He's positive for the group, a natural leader, a winner, how he trains.
"For me, it's a wonder to have him in the team."
