"I felt so bad, I was in some pain and I could have cried," he told Arsenal.com. "Not tears for my shoulder but because I was going to go off. I was there, in the first-team and I was being forced off.
"I had been nervous at the start but I got a few good touches in and I was feeling comfortable. I was on for 20 minutes but it could have been more. I was disappointed to be missing out on game time with the first-team."
The attacking midfielder added: "The day after, I was supposed to go back to Holland for my Christmas holiday, but I couldn't go! I needed to go and see the specialist, to have an MRI scan to see how bad it was.
"Luckily the person I saw said that there was no big damage around the shoulder, to the muscles and other parts, so I didn't need to have an operation. I would have been out for three months if I needed one so thankfully without it I was out for only one month."
