Arsenal will bid to reach the Champions League quarter-finals for the first time in 14 years when they battle Porto this week.

The Gunners went top of the Premier League following results at the weekend but this European challenge is arguably their biggest game of the season so far.

A late goal from Kai Havertz was enough for Arsenal to edge past Brentford on Saturday.

Liverpool's 1-1 draw with Manchester City a day later then kept the club ahead on goal difference.

The only blip in Arsenal's recent form came in a narrow 1-0 defeat away to Porto last month, with the north Londoners now at risk of another premature Champions League exit.
