Bukayo Saka warned Arsenal's title rivals that the Gunners are back to their best after they plundered five goals for a second game in succession.
Arsenal endured a difficult period between the October and November international breaks, failing to win any of its four league games during that period, but has impressed since the resumption of the club season.
Mikel Arteta's men beat Nottingham Forest 3-0 at the Emirates Stadium last weekend before a 5-1 win away to Sporting Lisbon in the Champions League and a 5-2 win at West Ham on Saturday night.
Saka scored and contributed to three more goals against the Hammers, and after the match vowed that the team is ready to go on a run.
"The last three games, we’ve been back, back to our best, back to our best way of playing," said Saka. "We’re fluid, we’re dynamic and you can see the movements, the rotations, everything looks good. We need to continue like this, we played three good games but we know in this league it’s not enough."
Of his own form, Saka told club media: “I’m happy so far but you know, I have to keep going. I can’t get complacent. It’s a long season and we’re only in November so, I need to continue like this. It was a lot of fun, [we scored] a lot of goals and, yeah, we enjoyed it.
“We’ve built a lot of momentum now, we’ve played really well the last three games, not just the results were good but also the way we played so we’re happy, we’re confident and we’re going to take it into the next game which, we know is a big one [against Manchester United on Wednesday]. We’re feeling good, we’re feeling ready for it, confident, so, let’s go.”
Arsenal boss Mikel Arteta agreed with his winger's verdict on Arsenal's recent upturn in form, saying: “We’ve got some momentum. I think we have some flow back, a real determination; winning consecutive matches against three opponents is great, and we’re going to enjoy tonight and watch a beautiful game of football tomorrow.
“We are in a great moment right now, but in football, be on your toes and prepare the best possible way for tomorrow. Because it is so competitive this league, the opposition that we’re playing every three days, that’s the only thing that you can do. We can analyse a lot of things to improve today, again tomorrow.”
