Captain Carlos Valderrama has insisted the squad will not allow the absence of banished striker Faustino Asprilla to affect their performance here tomorrow.

Tunisia lost 2-0 to England in their opening Group G tie in Marseille and the North African side's Polish-born coach Henri Kasperczak believes Colombia's recent off field distractions may make his task all the easier. ``The Colombians were a dangerous proposition,'' he said. ``It remains to be seen whether they still are.''

Asprilla, the gifted former Newcastle striker now with Parma in the Italian league, was so appalled at the lack of service he received from the ageing Valderrama and teammates when he was posted as the lone striker against Romania, that he staged a public revolt after being substituted.

Coach Hernan Dario Gomez told him topack his bags and go home. An announcement from Gomez in the wake of the Asprilla affair that he was resigning after the World Cup did nothing to lift the poisoned atmosphere.Some players thought that Asprilla, who later apologised should have been given a second chance.

Valderrama says the Tunisia match is win or bust.
