Tottenham manager Juande Ramos is refusing to allow his players to think about their trip to Wembley before they secure a spot in the last 16 of the Uefa Cup.
Spurs secured a 2-1 victory against Slavia Prague in the Czech Republic on Thursday to earn slim a first leg advantage.
Goals from Dimitar Berbatov and Robbie Keane handed Tottenham the lead, but goalkeeper Radek Cerny then fumbled a cross to allow Slavia's David Strihavka the simple task of prodding in a consolation.
And with their European progress yet to be assured, Ramos is insisting his side concentrate on next Thursday's second leg before they consider their Carling Cup final clash with Chelsea the following Sunday.
"Before the cup final we have the second leg of this tie and all our efforts are now concentrated on this match, and before we finish it we won't be thinking about Wembley," said Ramos.
Ramos, though, has refused to blame Cerny and believes the shot-stopper - who is on loan with Tottenham from Slavia - could have been nervous while playing against his parent club.
"The mistakes can always happen, that is the world of football," added Ramos. "This time it was the turn of Cerny.
"It's quite possible that he seemed really nervous after the goal, more than normal.
"It must be very difficult for him to be at his home ground to play against his former club."
