His record at Porto was outstanding, in one season he led them to a treble going undefeated in the league. Not bad for a 33 year old with only one season in club football behind him (did brilliantly in that as well, saved the winless Academica from relegation).
he will do amazing with Zenit.....move back to the prem, and do very very well, and then take a massive dump in the home changing rooms when he takes his team to WHL and Chelski
