Fulham striker Bryan Ruiz has praised "exciting" Arsenal starlet Joel Campbell and believes the teenager will be a smash hit next season.
Campbell, 19, scored the only goal for Costa Rica in Wednesday's 1-0 win over Wales at the Millennium Stadium.
The striker, who joined Arsenal last summer, also scored in a 2-2 draw with Spain in December and Ruiz has believes he is destined to be a future star in the Premier League.
Campbell is currently on loan at French side Lorient, where he has scored two goals in sixteen league appearances.
"You will see that he will get a chance in the next pre-season. So it is up to him," Ruiz told the Daily Mail.
"Joel is an exciting player. But in Arsenal they are very smart. They have placed him in a team to teach him, as he is young, so he does not have to go too fast.
"In Costa Rica we don't have many players playing here in the best leagues so he has to adapt to those things.
"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."
Meanwhile, Arsenal manager Arsene Wenger has admitted that both Thomas Vermaelen and captain Robin van Persie are doubts for Saturday's lunchtime kick-off against Liverpool at Anfield.
Van Persie played for Holland in their 3-2 win over England at Wembley on Wednesday despite carrying a groin problem.
The forward was withdrawn at halftime but Wenger revealed the 28-year-old would be assessed ahead of tomorrow's clash.
'We have a problem with Vermaelen that we have to assess today. Van Persie has a little groin problem that we have to assess,' he said.
