Gerrard said from Hong Kong: "I was impressed with Fernando when we signed him, but in the short period of time I've worked with him I've been impressed even more.
"He's not come in as a star name. He's come to work hard. He's the type of player we need, and we're excited to have him. Hopefully, he's going to be the one who scores all the goals to win us trophies.
"He'll have quality players here who can set him up and he can achieve everything he wants here."
