Bamford, Ayling set to miss out through injury. Tierney doubtful for Arsenal.
Arsenal will be looking to advance to the quarter-finals of the EFL Cup when they welcome Leeds United to the Emirates Stadium on Tuesday night.
The Gunners will enter the contest off the back of a 3-1 win over Aston Villa in the Premier League on Friday, while Leeds played out a 1-1 draw with Wolverhampton Wanderers on Saturday.
Mikel Arteta’s side, who are currently ninth in the Premier League table on 14 points, recorded a 3-0 victory over AFC Wimbledon in the last round of the EFL Cup to progress to this stage, with Alexandre Lacazette, Emile Smith Rowe and Eddie Nketiah on the scoresheet.
Leeds, meanwhile, will enter Tuesday’s contest off the back of a 1-1 draw with Wolves in the Premier League on Saturday; Hwang Hee-chan’s 10th-minute opener appeared to be securing all three points for the visitors at Elland Road, only for Rodrigo to level the scores with a 94th-minute penalty.
Marcelo Bielsa’s side needed penalties to overcome Fulham in the last round of the League Cup after a goalless draw at Craven Cottage, but they put three unanswered goals past Crewe Alexandra in the second round.
Mikel Arteta is likely to make changes for the Carabao Cup fourth-round clash.
Gabriel Martinelli, Mohamed Elneny, Bernd Leno, Cedric Soares, Ainsley Maitland-Niles, Nicolas Pepe, and Rob Holding could all be in line to feature.
Granit Xhaka will definitely miss out as a long-term absentee, while Kieran Tierney is unlikely to be risked due to an ankle injury.
Leeds could also make changes for this one.
Luke Ayling, Junior Firpo, Robin Koch, Raphinha, and Patrick Bamford will all miss out through injury, while Marcelo Bielsa could rotate his squad.
Tyler Roberts, Crysencio Summerville, Adam Forshaw, and Charlie Cresswell could all be handed an opportunity in the first team.
The match will kick off at 7:45 pm WAT.
