Arsenal are set to square off with Portuguese giants Porto on Wednesday evening in the last 16 of the Champions League - let's take a look at which players the Gunners will be able to call upon and who is set to miss out.
Arsenal have five players who are either out of action or whose availability is currently unclear. Porto, meanwhile, have three players who will definitely miss out - another is a major doubt. Both teams will be without key players in this colossal clash - but which of the two will enter the second leg with the advantage?
1. Jurrien Timber - out
Jurrien Timber remains a long-term absentee after being injured at the dawn of the campaign.
2. Oleksandr Zinchenko - out
Oleksandr Zinchenko is out of action with a calf injury.
3. Thomas Partey - doubt
Thomas Partey could feature against Porto, but it seems highly unlikely. He's expected to be back at the weekend against Newcastle.
4. Takehiro Tomiyasu - doubt
Another player who isn't expected to play, Tomiyasu probably won't be risked against Porto.
