Former Barcelona captain Carles Puyol says Manchester City boss Pep Guardiola will change football in England but said he facing the biggest challenge of his career.
Puyol and Guardiola won three La Liga titles and two Champions League together during the Catalan's four-year reign at Barcelona.
Guardiola also won three Bundesliga titles with Bayern Munich but Puyol said the direct football in England will be a test for his favoured tactical approach.
"It's the biggest challenge for Guardiola, but I think he will change football in England," Puyol was quoted as saying in the Daily Mirror.
