The Hammers struggled for goals in the absence of Arnautovic and Lanzini to injury but the pair are set to be available for their next Premier League outing when they make the trip to Anfield to face Liverpool on February 24.
With Arnautovic, Lanzini and Hernandez all set to feature against the Reds, Adrian believes his side are a different animal when they have the trio available.
“Marko is a great player, everyone knows that, and you absolutely miss this kind of player [when he is out injured] and you have to adapt and work in a different way, but now we have Marko back and Manu is ready to come to the team,” he told West Ham TV.
“We hope all the injured players will come back as soon as possible and we can work all together until the end.
“Chicharito (Hernandez) is a top striker. I’ve got a great relationship with him and he deserves his goals because he is a hard worker. I’m really happy for him and for the team.”
Uwe Rosler was sacked by Fleetwood following a 3-0 reverse at Doncaster which condemned Town to a seventh straight defeat in all competitions.
Cambridge interim head coach Joe Dunne was pleased with how his side adapted to beat Grimsby 3-1.
