Fulham striker has revealed that Arsenal fans can expect good things from his Costa Rican teammate Joel Campbell in the future.

Ruiz assisted Campbell's goal during the 1-0 victory over Wales on Wednesday and believes that the 19-year-old will prove to be a success at the Emirates.

The Fulham star said: "He is a very good player, you can see that, and it is because of that Arsenal got him.

"You can see the way that he moves, he has qualities, and he played in the Costa Rica youth team. Arsenal know that and he will get his chance.

"He needs time to adapt. He did very good against Wales, everyone can see that. He will get his chance but he needs time."

Campbell is currently on loan at French club Lorient.
