Luka Modric wants Croatia to guard against complacency ahead of their Euro 2012 playoff second leg with Turkey on Tuesday.
Slaven Bilic s Croatia side registered a 3-0 win away from home in Friday s first leg.
They will head to the return match at Stadion Maksimir in Zagreb as favourites to reach next year s finals in Poland and the Ukraine.
Despite their commanding position, Tottenham Hotspur midfielder Modric has urged caution and insists his team cannot afford to relax against Turkey.
We ve only done half our job, Modric told Uefa.com.
We really need to rest a bit in the next few days and prepare well for the second match.
The most important thing is that we stay focussed now. We can t relax, even a little bit. It could be very dangerous.
Modric felt Croatia s performance at the Turk Telekom Arena was their best since defeating powerhouse Germany 2-1 in the 2008 European Championships.
The last time we played as well as that was against Germany at Euro 2008, he said.
That s a fact and we shouldn t run away from it.
We re back and we played like a great team again, in every position.
We need to repeat that in Zagreb and seal our spot at the Euro, where we belong.
Turkey coach Guus Hiddink conceded his team s chances of overturning the deficit are slim.
Let s face facts it s difficult, almost impossible, to qualify, Hiddink said.
I expect the players who take their place to play for their honour, for themselves, for their country.
