Betting & Match Odds
As you'd expect, Arsenal are strong favourites to win the game, with bet365 giving odds of 1/9 on a Gunners victory. Blackpool's chances of winning are slim at 25/1, but a draw is available at 10/1.
The Carabao Cup may be considered somewhat of a reprieve for Arsenal following a gruelling run of fixtures in the Premier League and Europa League, but Emery is adamant that it is a "very important" trophy.
The Gunners boss has indicated that he will use the fourth round against Blackpool as an opportunity to elevate young players who he feels have earned the right to perform on a senior platform.
"We are going to have a mix in order to get the best performance against Blackpool, to respect them," Emery told reporters in the pre-match press conference.
"For us, the Carabao Cup is very important. It’s an opportunity to win a trophy and for tomorrow, a chance to play in front of our supporters at Emirates Stadium in this competition."
Emery will, no doubt, have one eye on the impending visit of Liverpool, which is scheduled for this Saturday, but there will still be room for a backbone of first-team regulars to offset the expected injection of youth.
Having put together a winning streak of 11 games prior to their draw with Crystal Palace, the Spaniard will be keen for his squad to resume that habit once again.
