Messi insists Aguero is one of the world´s best strikers, as Manchester City host Barca

Barcelona star Lionel Messi has backed Sergio Aguero, describing him as one of the world’s best strikers.

The Argentina team-mates will be on opposite sides at the Etihad Stadium today when Manchester City host Barca in the Champions League.

Aguero was controversially named as a substitute for City’s 4-0 loss at Camp Nou in the reverse fixture earlier this month and has not been an automatic selection under Guardiola.

But Messi, who enjoyed sensational success under the Catalan manager during his Barca tenure, has no doubts over Aguero’s quality, ranking him with the game’s top centre-forwards like club colleague Luis Suarez.

“Kun is a very simple and easy-going person, a great lad and, as a striker, one of the best. As is Luis [Suarez],” Messi told The Sun.

“They are different but, if you want to look at it like that, either of them can decide a game. They are both very decisive.”

The Argentina captain feels Barca have tweaked their style of play under Luis Enrique, but does not think things are that different from Guardiola’s reign, which came to an end back in 2012.

“In reality, the system of Barcelona is something that everyone knows,” said Messi.
