Sales of Sergio Aguero shirts increased by a staggering 1,200 per cent in the days after Manchester City announced his impending departure this summer.
Aguero is leaving City when his contract expires and Pep Guardiola claimed on Friday that he would have no problem with the striker joining a Premier League rival.
Chelsea have kept an eye on Aguero's situation, with interest in the 32-year-old also coming from abroad.
'All of us wish the best for him,' said Guardiola. 'We'll be delighted with the decision he takes, the best for him and his family, to find the best for Sergio for the last years of his career.
