Barcelona coach Xavi was delighted with his new players after their 1-0 defeat of Real Madrid in Las Vegas.
Raphinha struck the winner for Barca, with Robert Lewandowski making his debut.
Xavi said, “Raphinha is capable of making a difference and Robert is a world star who has adapted quickly.
“At the same time, he will give competition upstairs and everyone will wake up a little.”
Asked about Sevilla defender Jules Kounde, Xavi added: “We can’t talk about players who aren’t here. We will try to reinforce ourselves so that there are two position level players. At the moment, nothing can be said.”
