"Javier has always been a very important player for us".
"We need to analyse the goals, have a look again at the mistakes we made, see where we need to improve".

After the game, Benitez acknowledged the threat that Hernandez, Anderson, Marko Arnautovic and Robert Snodgrass posed on the break.
"Still I think we did well enough to create and then maybe to score, but we didn't do it and the second goal, it was very hard for us".
Hernandez missed two more good chances before doubling West Ham's lead, running onto Arnautovic's flick-on and beating the advancing goalkeeper Martin Dubravka easily.
"They have some quality players on the counter-attack, but we were trying to push them and trying to create some chances".

Ayoze Perez headed straight at keeper Lukasz Fabianski from Matt Ritchie's inviting 22nd-minute free-kick as the Magpies responded, but the visitors threatened repeatedly on the break and it took a good block by Javier Manquillo to deny Arnautovic after he had run on to Anderson's through ball and rounded Dubravka.
The task for West Ham the defender feels will be to play with full concentration for the full 90 minutes and not drop important points that they have been dropping this season.
"Every top team needs two or three key players to make things happen, and he can be one of those for us".
