Gaetan Bong has warned against under-estimating the size of the task facing Albion against Arsenal on Sunday.

The Gunners' form has been suspect as they head for the Amex, especially away from the Emirates.

They have not won away in the Premier League this year and have been beaten by Bournemouth, Swansea and Spurs in their last three away games.

Chelsea were winless in five matches in all competitions before thrashing Albion 4-0 at the Amex in January.

Bong told The Argus: "It's never a good time. We were saying the same when we played Chelsea. They weren't good, they came to us at home and beat us.

"The top teams have a lot of (quality) players. We just need to be focused on us and what we can do. It's going to be hard but we'll see.

"In the last ten games any team will have pressure. It's the last step. We have to take points.

"Arsenal at home is a massive one but every Premier League game is a big game for us."
