So this was it, Pep Guardiola’s chance to finally speak freely about his departure from Manchester City, and the decisions and emotions that led to it.For months, he had to stick to the line that he had one year left on his contract, his way of denying the growing rumours that he would leave this summer, but on Friday morning came the confirmation that this will be his final season in Manchester after all.“Aston Villa, guys, allez,” he said as he sat down, referencing Sunday’s opponents, the nominal reason for the press conference. A little bit of humour, given everybody was there to pore over his decision. He proved to be good value, as ever, talking about phone calls from Kevin De Bruyne, a text from Sir Alex Ferguson, and that his dad, at 94 years old, will be at the Etihad Stadium for his farewell.He confirmed that his mind has been made up for some time and admitted that he would not have the energy for one more season. In recent weeks, he has spoken emotionally, arguably more emotionally than here. Perhaps that was because it was all a secret, that he was talking about things such as Bernardo Silva and John Stones’ goodbyes, but in reality, he was talking about his own.Why now, he was asked. “It’s time. It’s not wake up and say, ‘Now is the time to leave’ — it is a process that I felt for a while.“Listen, this job is every few days for many, many years. Selhurst Park, Anfield, Madrid and Madrid and FA Cup and brrrr. And now I have to live my life and see what happens.“Ten years is a lot of time, and I think the club needs a new manager, new energy with these incredible players that we have right now, and start to write another chapter.”(Glyn Kirk/AFP via Getty Images)Jurgen Klopp had admitted to running out of energy when he announced his exit from Liverpool two years ago, and Guardiola said that it is the same for him. “Absolutely, absolutely. I had, I have, (but) I will not have. It’s simple. I feel I will not have the energy that’s required daily, every three days, expectations to fight for the titles, and being in front of the players. I know myself, I have energy this season, but I feel that I will not have (more).”News of Guardiola’s impending departure was broken on Monday night, but the week ticked by without anything official, which gave fans hope of a U-turn or that the speculation was false.But everything burst into life on Friday; he told his squad in the morning, after they had been left in the dark for a few days, before the news was made public. There was an emotional video that he narrated, having scripted it himself.
