Fornals concedes the style of play is very different compared to what former boss Manuel Pellegrini demanded.
He told Marca: "In the last games with Pellegrini I scored my first goal and gave several assists. Now with Moyes we have changed the system.
"Maybe we don't have the ball so much and we prioritise reaching the area fast and scoring goals. I still play on the left wing and I am delighted to be the protagonist again and looking forward to helping my team.
"Name by name we have a good team. Many Premier or LaLiga teams would sign West Ham players. We have had many ups and downs. We started well, in the top five, but then we deflated and now we have to fight to be next year in the Premier."
