West Ham United boss Sam Allardyce is backing their strikers Diafra Sakho and Enner Valencia to test Manchester City this weekend.
Sakho and Valencia were both on target in the 3-1 victory at Burnley last weekend and Allardyce will be hoping for more of the same when the Hammers host Manchester City on Saturday.
"From my point of view I thought it would have been a slower process but we wouldn't have expected Enner Valencia to make such a big contribution either," Allardyce said.
"The pair of them have hit it off together - it's not just the goalscoring, it's the energy they give the team which is very important in today's highly competitive game.
"Your energy, intensity and sprinting capabilities are very important today in breaking down defences.
"They turned the game for us against Burnley because we weren't very good in the first half and then two beautiful crosses creates two goals.
"That's what you wish for, that's what you dream of as a manager in the Premier League."
