Pep Guardiola has challenged Gabriel Jesus to respond to the task of dislodging Sergio Aguero as Manchester City’s first-choice striker.It was a mission Jesus revelled in immediately after his arrival in Manchester in January 2017, with City’s all-time top scorer Aguero forced to bide his time on the bench in a number of high profile clashes – most notably a 2-1 derby win at Manchester United in December of that year.But Aguero has knuckled down to adapt his game to Guardiola’s specific demands when it comes to centre-forward play and is thriving under the Catalan, as evidenced by his stunning opening goal in last week’s 2-1 win over Premier League leaders Liverpool.

In part of our period together he played important games before Sergio because in that moment he was better than Sergio.”People were saying my relationship with Sergio was very bad, it was not correct, but I tried to be honest.”When I saw Gabriel in that moment he was playing more minutes and more important games than Sergio because in that moment I believed.”But I believe Sergio is an important player when fit and [Jesus] has to fight to win his position.”Aguero, 30, has 10 goals in 17 Premier League appearances this season and 14 in 22 across all competitions.
