Mikel Arteta has thanked not only Arsenal but also Liverpool's staff, players and fans for their support after he was injured in Saturday's game at Anfield.
The Spaniard, who was at Everton for six years before leaving last summer, collided with Jordan Henderson in the second half and required lengthy treatment before being carried off on a stretcher.
He was taken to hospital in the city as Arsenal's medical staff were concerned about a possible neck injury but he was released later that day.
Arteta has now expressed his gratitude to everyone who looked after him and those who have sent their best wishes.
The midfielder is looking forward to getting back to action as quickly as possible, although he will not play for a week so that he can recover from concussion.
"I just want to take this opportunity to thank everyone for their help and friendship towards me on Saturday," wrote Arteta in an open letter on Arsenal's official website.
"After my accident on the pitch, the Arsenal medical staff did a great job, together with everyone at Liverpool Football Club.
"From Anfield, I was taken straight to the Aintree University Hospital, where they checked me, just as a precaution.
"Everything was fine and I was able to travel from the hospital and join up with my team-mates for the train journey back to London.
"I've since looked back at the TV images of when I was being taken off and just want to show my appreciation to the Liverpool fans at Anfield.
"It is touching to receive that response from the fans of a great club when I am leaving the pitch injured. Thank you.
"I also want to thank Pepe Reina and the Liverpool players who have sent me messages of support and friendship, this again is really touching and just shows class from a great football club.
"And very importantly, a message to all the fantastic Arsenal fans, not only all those at Anfield on Saturday who were brilliant, but also those who have sent me many messages since Saturday.
"It is hugely appreciated. I cannot tell you how much this means to me.
"It must have looked very serious to everyone as I left the pitch on a stretcher, but I'm pleased to say that I'm fine now and hope to be back on the pitch very soon. Thank you everyone."
