Pep Guardiola ushered in a new era at Manchester City promising "hugs and kicks up the backside" as his club welcomed the manager they believe will make them a global superpower. Manchester is bracing itself for the opening salvos in the battles of the superstar coaches, with Guardiola's unveiling coming 48 hours before rival Jose Mourinho's formal introduction at Old Trafford.City believe they have appointed the world's No1 manager, but despite arriving in England with a staggering 22 major trophies, the 45-year-old former Barcelona and Bayern Munich manager claimed he was moving to Manchester City with something to prove."That is why I am here. For the challenge. I proved myself in Catalonia, I proved myself in Germany, and I want to prove myself in England," he said."With my staff and players we want to try to make Manchester City play in a way to make people proud. At the end what I want is for our supporters to enjoy and be proud of what we did. I can't do that alone."Guardiola greeted City fans for the first time at Manchester City's academy in what was the most choreographed unveiling of a manager English football has witnessed.His appointment was billed as "the next phase of Manchester City's history" as questions were invited from supporters in the culmination of two days of fan-orientated club events.The greatest applause was when the Spaniard offered an insight into his style."First I have to meet the players and know them - not from TV - and speak with them, hug them and kick their arse," he said to appreciative applause."Every manager in the world wants to improve their players, that is how to improve the team."I work like all managers. I have my point of view and how I want to see my team play but I need time. In the world we don't have time so we will try to create a good team as soon as possible."Our body language at first is the most important thing and then the rest will come along."I know the players. I played against Manchester City many times and I know their quality, but they have to show me again. The past is the past. People do not come here to remember what we did but to try again."..
