Manchester City v Brentford (Tue, 19:30)
Brentford
Brentford boss Thomas Frank on repeating last season's shock away victory over Manchester City: "We hit a very high level . We need to play almost the perfect game. Especially in defence. I think we are good there generally, and don't give much away. But this season maybe given more chances and goals than usual. That's the big thing we need to adjust.
"I think the last 24 games I have changed my back three or four, or five with the goalkeeper, a lot of times. 19 times we played a different set-up at the back which doesn't help. There are things we need to avoid regardless of how many players we are changing."
