Christian Eriksen was at his brilliant best to help Manchester United achieve a 3-1 victory over Arsenal.

The Denmark international was signed on a free transfer this summer and he endured a shaky start to his career at Old Trafford.

Eriksen, like the rest of his teammates, really struggled in the 4-0 defeat away at Brentford and many questioned whether he still had the ability to succeed at a top Premier League club as a result.

But the former Tottenham Hotspur midfielder has silenced every single one of his doubters in recent weeks.

He was brilliant in the recent 2-1 win over Liverpool and took things up another level against Arsenal on Super Sunday.

Eriksen dropped a masterclass on the Old Trafford turf, assisting Marcus Rashford's second goal that secured a priceless 3-1 victory and earning the Man of the Match award for his efforts.

Everything the 30-year-old did had a touch of class about it and Arsenal's midfield just couldn't cope with his composure on the ball and incisive passing through the lines.

Well played, Christian.

It's crazy to think that just over a year ago, Eriksen looked as if he would never play professional football again after he suffered a cardiac arrest in a group stage match against Finland at Euro 2020.

But now he's back running games between two Premier League giants - and also sharing funny moments with pundits in post-match interviews.

After his dazzling display against Arsenal, Eriksen spoke with the Sky Sports panel on the touchline and United legend Roy Keane couldn't resist bringing up his performance in a 5-1 win over Ireland that saw Denmark qualify for the 2018 World Cup.

Eriksen scored a hat-trick and Keane - who was his country's assistant manager at the time - certainly hasn't forgotten about it.

Keane said: "I have no questions because I'm still upset over Dublin, when you scored for Denmark. I'm still upset with ya."

To which Eriksen cheekily replied: "I thought so! It was a good night out afterwards in Dublin."

We bet it was, Christian.

Keane may never forgive Eriksen for ending Ireland's 2018 World Cup dream, but he must enjoy watching him strut his stuff in a United jersey - especially against Arsenal.
