Neto scored against his former club, with Garnacho creating the chance.
The Portugal winger said afterwards: "I’m really pleased for Garna and he did a great job for us.
"He’s been working really hard and he’s getting his chance in the team and he’s taking it right. Two assists in this game, a goal the other night in the Champions League and we’re really happy with him.
"He’s settling in well and you can see he is working really hard for the team both on and off the ball, he’s doing a really good job."
Chelsea manager Enzo Maresca also said of former Manchester United winger Garnacho: "Garna played a fantastic game on the ball, but he was also top without the ball. Pedro Neto was exactly the same and this is what we need from our wingers.
"He (Garnacho) arrived here from another club where he was not training 100 per cent, so his physical condition was not good. Slowly, slowly and now it’s better.
"He is doing very well on the ball and is doing well off the ball. He knows that, to play with us, he has to be good on the ball and off the ball. We are very happy with him in this moment."
