Fernando Torres has warned European champions Spain to beware of a Turkish backlash on Wednesday, when the two sides meet in a 2010 FIFA World Cup South AfricaTM qualifier.
Spain squeaked past Turkey 1-0 on Saturday, with a goal from defender Gerard Pique, but the visitors gave their hosts a tough time of it before succumbing.
With Bosnia-Herzegovina managing a surprise win in Belgium to go provisionally second in Group 5, Turkey, a point further back in third, now have to make up lost ground.
Spain lead with a perfect 15 points, but Torres says this is no time for complacency.
"We must be humble in taking on any rival and all the more so with Turkey as they have a great team," said the Liverpool striker.
"They made things tough for us last Saturday and they will do all the more so on Wednesday.
