The Chilean was in place as Manchester City manager for three years before making way for Pep Guardiola. Manuel Pellegrini had an eventful three years in charge of Manchester City .
Brought in to bring some much-needed calm after Roberto Mancini’s reign fell apart, the Engineer orchestrated an exhilarating first season in charge that brought a league and cup double from an incredibly attacking team .
He would be unable to claim another league title during his time at the Etihad, but did add another league cup in his final season in charge as well as a run to the Champions League semi-finals – the furthest City have ever progressed in the competition.
The failure to recognise how Champions League groups work in 2014 when City needed another goal at Bayern Munich proved costly in the last-16, FA Cup defeats to lower-league teams Wigan and Middlesbrough were avoidable and there was severe criticism for throwing away their fifth-round tie with Chelsea when five youngsters were thrown into the team.
As far as Pellegrini is concerned though, his “mistake” came in his final season when the manager announced at the end of January he would be succeeded by Pep Guardiola at the end of the campaign.
City won only four of their next eleven games in all competitions, crashing out of one trophy and allowing Leicester to shatter their momentum in the Premier League.
And while they did enjoy a run to the last four of the Champions League, their limp semi-final performance against Real Madrid was heavily criticised in public by chairman Khaldoon Al Mubarak in his annual review.
Pellegrini had said at the time he wanted to let everybody know so that nobody was left in the dark about what was going to happen at the club.
However, looking back at the decision the 64-year-old believes it inevitably took the edge of his squad for the rest of the season to leave an unsatisfactory end to a tenure that had got off to such a good start.
“I learned something from the experience in my final season,” he told the Coaches Voice .
“It’s the same in the case of Sir Alex Ferguson. With all the experience and influence he had at Manchester United, he made his first retirement announcement several months early. I think he always described it as a mistake in his career. I also describe mine as a mistake.
“Because, as much as you don’t want it to be this way, the group has a tendency to relax. To start thinking about the next step.
“That’s why I say that as a manager you have to keep on learning. Carry on reading.”
