Leeds United manager Marcelo Bielsa is well aware of West Ham's attacking depth.
The Whites welcome David Moyes' side to Elland Road on Friday night.
Speaking in his pre-match press conference, Bielsa said of the eighth-placed Hammers: "The teams that are stabilised in the Premier League, they have the possibility to correct the aspects that they feel are weaknesses.
"If a team continues with the same coach then these improvements are more visible.
"What West Ham have, is that they have two players per position in their attacking positions who are similar or of the same quality.
"For example West Ham don't have in their XI Andriy Yarmolenko, Manuel Lanzini and Michail Antonio.
"They loaned out Felipe Anderson, this gives you the idea they're a team that has a good offensive potential.
"They have a structure of seven defensive players which is also very solid.
"They also have a clear view of when they need to attack, defend, and when they need to play, which are all aspects of a good coach."
