Emery’s side suffered a 1-0 defeat on its trip to Monaco in the UEFA Champions League in midweek, but is are looking to go five games unbeaten in the English top flight, having held Arsenal to a thrilling 2-2 draw at Emirates Stadium last time out.

“Consistency is our objective, and we can improve on it, only facing each match and focusing on each match,” Emery, whose side sits eighth with 36 points heading into the weekend, said.

“If we are not winning Sunday [Monday AEDT], again, we are not being consistent at home. We lost in Monaco after two very good matches we played at Everton and Arsenal.”

Villa has strengthened its squad in the January transfer window, with 21-year-old full-back Andres Garcia joining from Levante while centre-back Diego Carlos has left for Turkish side Fenerbahce.

“He is a right full-back with potential. He is a young player. He was progressing so quickly. Hopefully, we can progress quickly in his adaptation, and how he can understand everything in the Premier League about the level we have,” Emery said of the new signing.

The Spaniard also noted that Villa is open to further business during the window.

“We are open to trying to improve the squad until the last moment, and as well, we are open in case someone is leaving,” he said.

“Of course we are also focusing on which players could have the potential to replace Carlos.”

Meanwhile, West Ham boss Graham Potter is also on the search for firepower in attack, with Michail Antonio and Niclas Fullkrug among those not available to him.

"At this time of year there's a lot of speculation but we just have to ignore the noise, help the players and keep working," Potter said.

"If we're in a position to do business, we'd like to. Our goalscoring in general is okay, but we'd like to do certain things better. We're a bit light but there are a lot of factors to consider."

The former Brighton and Hove Albion boss, however, had good news to share when it came to Jarrod Bowen and Crysencio Summerville.

“Bowen has been integrating into the group. He's had a couple of sessions, but it's still early. It's important we don't rush it. It's the same with Summerville. He’s had a couple of sessions, but we need to see,” he said. 

“It's nice to have them back amongst it, but it's important we manage it properly.”

West Ham has 26 points from 22 matches and is 10 points clear of 18th-placed Ipswich Town as it prepares for its first away league game under Potter, who replaced Julen Lopetegui earlier this month.
