Arsenal will follow up their biggest win of the season last weekend with a tricky visit to a West Ham United side that has already registered two victories over the Gunners this campaign.

The third-placed Gunners (49 points from 23 matches) earned a comprehensive 3-1 victory over Liverpool on February 4, tightening the three-team race atop the English Premier League.

Bukayo Saka, Gabriel Martinelli and Leandro Trossard scored in the fully deserved victory, one in which coach Mikel Arteta's side held Liverpool to only one shot on target.

Arsenal logged their third consecutive league win after they had lost three straight in all competitions, a slide that began with a 2-0 home league defeat to the same West Ham side they will face on Sunday.

Arteta attributes that sudden reversal in form to a continued belief in the team's approach. "It's the reactions of the players, the staff, our supporters as well," he said.

Saka now has eight goals and seven assists in the league to lead the Gunners in both categories, and Martinelli has scored three of his five league goals since New Year's Day.

Seventh-placed West Ham (36 points from 23) are winless in six matches across all competitions since their previous win over Arsenal. However, they could yet make it a three-game season sweep after they also won these sides' League Cup meeting 3-1 at home back on November 1.

They would have to do so without Lucas Paqueta, who left these teams' previous meeting with a calf injury.
