Glasgow: Barcelona coach Tito Vilanova is refusing to consider signing taller players despite his team’s ongoing problems in defending set-pieces.

The tournament favourites were overpowered by hosts Celtic in a 2-1 Champions League defeat on Wednesday when Barca’s decision not to sign centre backs in the last transfer window was again exposed following injuries to the backline.

Victor Wanyama headed in Celtic’s first midway through the opening period and Tony Watt scored a second after a quick break before Lionel Messi pulled one back as Barcelona failed to convert their domination into goals.

“We could sign taller players but I like to have fun when I’m on the bench and this is the way that we play,” Vilanova said.

“We have suffered from set-pieces after losing Eric Abidal and Seydou Keita but we can only try to attack more and not let them have any corners.”
