Manchester City manager Pep Guardiola has praised striker Sergio Aguero after his brace in Saturday's 4-0 win over West Brom.
The Argentine forward scored in the 19th and 28th minutes at the Hawthorns, with Ilkay Gündogan also hitting a brace later in the match.
"We need Sergio," Guardiola said. "We know how important he is for us. He is part of the history of this club and will be forever but I would like to help him.
"He can still write the most brilliant pages in his career in this club. All of us we are there to help him and of course the first goal is really good and the second as well.
"He's one of the best. But I want to help him be much, much better. That is my target.
"Just to see how many goals he's scored here in the Premier League and how difficult it is, and that's why I'm so, so happy for him because he is one of the nicest people I have ever met."
