Speaking on Sky Sports after the game against Manchester United on Sunday, Roy Keane said: "Arsenal in a great place. There's a good atmosphere, they've got momentum, Bukayo Saka and Eddie Nketiah were brilliant.
"There's a nastiness to them because they know what to do on that football pitch. It was a big challenge for them today. It's a tight game and they're up against it, you look at the personality of the team, the characters.
"They're all good players and we see that week in and week out, but could we see the other side of it? We did today. Arsenal have momentum, there's good experience, good youth, there's pace, they had good options off the bench.
"They're in a great place. There is a long way to go, but if you said at the start of the season they'd be where they are, you wouldn't believe it. They've got momentum and it will take a lot to stop them.
"They were under pressure with Manchester City winning today and the other night. They deserved the victory. They have answered their critics and showing them they have learned from those mistakes and are a stronger group."
Arsenal secured a vital 3–2 victory against Man United on Sunday to keep their five-point lead over Man City while still having a game in hand.
Up next for the Gunners in the Premier League is a trip to Everton on February. The home clash against Man City will take place on February 15.
