Arsene Wenger is positive regarding the fitness of two of his stating midfielders against Galatasaray.
The win over Galatasaray as a huge confidence boost for Arsenal, even if ultimately it did not help them finish top of their Champions League group.
So the last thing they would have wanted was for a key player to pick up an injury.
Aaron Ramsey's half-time withdrawal raised the possibility of this being the case, but Arsene Wenger was positive in his post-game press conference, also addressing Mathieu Flamini who was withdrawn too.
He told Arsenal.com: "Ramsey had a hamstring, but should be alright for Saturday. Flamini had a calf, but should be ok."
Arsenal particularly need Ramsey's energy against Newcastle at the weekend, and taking him off early was sensible management from Arsene Wenger.
The Frenchman has already lost Jack Wilshere for the foreseeable future to injury, and cannot afford to take any risks with a player who is arguably an even bigger talent.
There was more good injury news for Wenger, with right-back Mathieu Debuchy playing 77 minutes in his first appearance since September.
