Walcott, now preparing to travel to Roma in the Champions League on Wednesday, said: "Eduardo's finishing is ridiculous - it is unbelievable to watch in training. He hasn't lost his touch and he never will. His goal is the best finish I have seen this year.
"I have learned from watching him while he has been injured, how well he took everything and how he smiles when he comes in every day.
"All the injured players lie on the beds together so there is a lot of banter around and that keeps everyone's hopes up. We train with fitness coach Tony Colbert and it's nice to have a bit of company but we all want to be back out on the pitch.
"As soon as we have got all our players back hopefully we will be flying. If we play football like we did today, we can beat anyone."
Walcott, who came on as a late substitute, said: "The shoulder feels fine. I still haven't experienced getting clattered yet so that's the next test. But if that happens, our new doctor Gary O'Driscoll has come from a rugby background and he says, touch wood, I'll be okay."
