Arsenal travel to Championship side Nottingham Forest on Sunday for their FA Cup Third Round tie at the City Ground, as they aim to win the competition for a record 15th time.
The Gunners have already made it to the semi-finals of the Carabao Cup and Mikel Arteta will be keen on a strong performance here, as they look to achieve further success in a cup competition this season.
And the Spanish manager will have a reasonably fit and healthy squad to choose from, in a game that will provide a tough test for the visitors.
There are little injury concerns for the Gunners, although a number of players have now left for the Africa Cup of Nations.
Here is all you need to know about the current state of play at the Emirates Stadium, as well as the potential return dates for those out injured.
Should Mikel Arteta play a full strength squad for this tie? Have your say in the comments section below.

Calum Chambers
Arsenal confirmed that defender Calum Chambers had contracted coronavirus ahead of their Carabao Cup quarter-final tie with Sunderland on December 21, and the 26-year-old has been out ever since.
There was optimism that he could have returned for the New Year’s Day clash with Manchester City, yet there was no place in the squad for him.
However, there is reason to believe that Chambers will be a part of the side to travel to Nottingham on Sunday, although a late fitness test may be needed to determine his involvement.
Sead Kolasinac
Defender Sead Kolasinac remains as Arsenal’s only injury concern at the club, as he continues his recovery from an ankle injury he sustained while on international duty for Bosnia-Herzegovina in November.
There has been no further update on his condition since the end of last month, which revealed that Kolasinac is “progressing well in the early stages of his rehab with the current aim to be back in full training in January."
Therefore, the Bosnian will once again miss out for this fixture, although it shouldn’t be too much longer before he trains with the first team again.

Gabriel Magalhaes
Centre-back Gabriel Magalhaes was sent off following two yellow cards he picked up during the New Year’s Day defeat at home to Manchester City.
His one match suspension would have been served for the Carabao Cup Semi-Final first leg against Liverpool on Thursday, although that has now been postponed.
This means that Gabriel will instead miss out on this weekend’s FA Cup tie at Nottingham Forest, although he will be able to return for the rearranged Carabao Cup tie at home to Liverpool next Thursday.

The following players will be unavailable for the Gunners over the next four weeks, as they compete for their countries at AFCON 2021.
