Spain head coach Vicente del Bosque admits he is concerned about the form of striker Fernando Torres ahead of Euro 2012.
The Chelsea forward has struggled since making a big money move from Liverpool a year ago and has found goals hard to come by.
Torres has scored more league goals for the Reds in 2011 than at his current club, where he has netted just three Premier League goals.
And Del Bosque admitted Torres' current club form is a huge worry ahead of next summer's tournament in Poland and Ukraine where Spain will face Italy, Republic of Ireland and Croatia in Group C.
He told AS newspaper: "It's a concern. He isn't playing much...there are five months to go to the European Championships, in which everything can turn around.
"But if the situation doesn't change it's going to be difficult for him. Fernando deserves respect for his career, and he has our confidence. But if he doesn't play...well, time will tell.
"If he plays and he's fine he will go to the Euros. He has contributed to the success we've had and he has some leeway."
Del Bosque also fears David Villa might not be fit in time for the tournament after he suffered a broken shinbone whilst playing for Barcelona earlier this month.
Del Bosque said: "He's Spain's leading goalscorer and he's got us out of trouble many times. Villa is important, but the doctors are optimistic and so is he. We'll see."
