Arsenal entered this weekend in fourth place in the race to qualify for next season’s Champions League.

However, it was the worst possible couple of days for Unai Emery’s side.

Tottenham won, Chelsea won, Manchester United won and Arsenal lost 3-1 to Manchester City.

It saw them slip to sixth, three points behind Chelsea and now 10 behind north London rivals Spurs.

But there were a few positives from their trip to the Etihad.

Despite a disastrous start which saw them go 1-0 down inside one minute, Arsenal performed well in the first-half.

But Sergio Aguero’s second goal shortly before half-time appeared to completely take the wind out of Arsenal’s sails.

They didn’t have a shot on target after the interval and Aguero’s hat-trick goal sealed all three points for the champions.

With 25 minutes remaining and the match effectively over, Unai Emery threw on Denis Suarez for his club debut.

Suarez had signed on loan from Barcelona on transfer deadline day and was returning to Man City, a club he spent two years at from 2011-2013.

Of course, coming off the bench when you’re 3-1 down against this Man City side on your Premier League debut was never going to be easy.

And it certainly wasn’t easy for Suarez.

And a video has emerged showing the 25-year-old’s performance at the Etihad.

SUAREZ'S ARSENAL DEBUT VS MAN CITY

Take a look:

Certainly not the greatest debut in the world but we can’t draw too many conclusions from Suarez’s first appearance in an Arsenal shirt.

However, there will undoubtedly be a fear that he’s not physically ready for the Premier League just yet.

On numerous occasions, Suarez was pushed off the ball far too easily - including against diminutive players such as David Silva and Sergio Aguero.

However, the Spaniard did look comfortable with the ball and will no doubt add some creativity to this Arsenal side.

At least Suarez can be safe in the knowledge that it won’t get any tougher than it did on his debut.
