Brentford are seeking back-to-back victories against the Manchester clubs, while City could extend their unbeaten run to seven games in all competitions. BBC Sport explores some of the key themes before Sunday's match.

"I thought we dovetailed nicely between enticing them and hurting them," said Brentford head coach Keith Andrews after his side beat Manchester United 3-1 last weekend.

It was undoubtedly the biggest win of the Irishman's short reign and it was underpinned by the performance of number nine Igor Thiago, who scored twice.

The Brazilian joined from Club Brugge for a then club record £30m in the summer of 2024 but barely featured last season because of injury. However, the 24-year-old has started this campaign impressively, with four goals in six Premier League outings.

Thiago lost his father at a young age and was required to provide for his family when he was just 13. Bricklaying and carrying fruit were some of jobs he did to earn money. Now he is one of Europe's most in-form strikers.

Of forwards to take 10 or more shots in the continent's top five divisions, only Harry Kane has a better conversion rate than Thiago and he is currently ahead of Robert Lewandowski, Julian Alvarez and Erling Haaland, his opposite number this Sunday.
