Arsenal will play arch rivals Tottenham in the Carabao Cup quarter-finals after surviving a late fightback from League One visitors Blackpool as both sides finished the game with 10 men.

Gunners full-back Stephan Lichtsteiner slid in his first goal since joining from Juventus before teenager Emile Smith Rowe doubled the Premier League giants' lead after half-time.

Arsenal were coasting until French midfielder Matteo Guendouzi was given a second yellow card for pulling back Jordan Thompson, leaving them facing the prospect of playing the final 35 minutes with a numerical disadvantage.

Blackpool, who are mid-table in the third tier, narrowed the gap when centre-back Paudie O'Connor headed in from a corner.

That meant the game turned into a nervier finish than it should have been for Arsenal, who fielded a much-changed side which still contained several experienced stars.

However, Blackpool were also reduced to 10 men with a few minutes left to play when O'Connor was shown a straight red card for scything down substitute Pierre-Emerick Aubameyang.

O'Connor's dismissal checked Blackpool's momentum as Arsenal stretched their unbeaten run to 13 matches under new manager Unai Emery.

The Gunners, who lost to Manchester City in last season's League Cup final, will host Tottenham in the last eight during the week of 17 December.

Should Emery focus on League Cup?

The debate over the importance of the League Cup in modern football has long continued, some managers moaning that the competition is a hindrance to their league ambitions, others seeing it as a great opportunity to claim silverware and build a trophy-winning culture.

Emery, who replaced long-serving manager Arsene Wenger in the summer, is likely to fit into the latter category.

The Spaniard has stressed the importance of the Carabao Cup as he looks to win a trophy in his first season at Emirates Stadium and treated the competition - and visitors Blackpool - with respect as he named a team containing seasoned internationals such as Cech, Lichsteiner, Aaron Ramsey and Danny Welbeck among his starting XI.

Youngsters like Smith Rowe and young Spanish defender Julio Pleguezuelo, making his Arsenal debut at centre-back, blended youth with experience as Emery was rewarded with a solid if unspectacular victory.
