A glut of injuries in January made that need even more acute but the Hammers were only able to bring in Joao Mario on a short term loan from Inter Milan and Jordan Hugill from Championship side Preston.
The Hammers were linked with more than 40 players during January. West Ham fans and pundits like Jamie Carragher have been critical of the club's owners David Sullivan and David Gold in the past for the very public way they do business.
Fan groups have been set up to campaign for a change of ownership after what they feel have been broken promises from Sullivan, Gold and vice-chairman Karren Brady over transfers, spending, ambition and the controversial move to the former Olympic Stadium.
Fans feel there is no clear transfer plan or philosophy in place at the club with a perceived scattergun approach to transfers a key bone of contention. They also feel Sullivan in particular has too much of a say when it comes to transfer targets and signings.
The surprise deadline day signing of Jordan Hugill only added to the feeling of bewilderment among fans.
But Sky Sports pundit Thierry Henry believes Moyes knows what he is doing.
"To play the Devil's Advocate I would like to think that David Moyes is trying to bring players that he likes," Henry told Sky Sports.
"Becaue he just arrived where they were all Slaven Bilic players, no disrespect to Slaven Bilic, but I'm sure he (Moyes) is going to try and bring players that can play his style, his way.
"I don't think it's just a (case of) 'I don't know what I'm doing'... actually he knows what he is doing, he's trying to get the players he wants to play his own way and obviously go on a good run."
The Hammers have turned a corner under Moyes and have lifted themselves up to 10th in a increasingly congested Premier League.
They remain in the dogfight, though, with a crucial run of games coming up, starting with Brighton away on Saturday.
