Nowadays 33 years is not too much of an age for a footballer. That is the age at which Sergio Aguero has announced an early retirement due to some kind of heart problems that gave him a scare a few months ago in an FC Barcelona match. Mr. Aguero´s Barcelona career was short (only four matches); but not so his 10-years at Manchester City where he became a legend. It also remains one of my own memories of Sergio Aguero when he brought the Premier League title to Manchester City with a memorable comeback against QPR. He ended up scoring 184 goals and winning five PL titles and one FA Cup during his time there.
As an Argentina fan I think his performances were more disappointing despite his 41 goals in 101 matches. He was part of the 2014 and 2018 World Cup sides, as well as won an Olympic gold medal in 2008 and the 2021 Copa America winners. But I think he never reached the high levels that he reached in both Atletico Madrid and Manchester City.
That said, Sergio Aguero is a great player that will be missed on the football pitches, and with gratitude wishing him a great post-footballing career!
