Eduardo impressed with a wonder goal in the 3-0 demolition of Burnley on Sunday.
Walcott 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.”
