West Ham sold strikers Diafra Sakho and Ayew to Rennes and Swansea respectively last month and only Joao Mario - on a short-term loan - and little known Championship striker Jordan Hugill were brought in.
Fans are far from happy with the club's co-owners David Sullivan and David Gold after another transfer window failure.
With a glut of injuries denying Moyes the services of the likes of Marko Arnautovic, Manuel Lanzini, Andy Carroll and Pedro Obiang supporters felt more quality needed to be added.
Few would disagree with the sale of Ayew, though, after the Ghanaian proved a £20.5 million flop during his 18 months in East London.
"When I look at my statistics and my time from August until now, I think I am one of the most efficient players, if not the most efficient," Ayew told Swans TV.
“I am not one of the players who played the most games, but I have no regrets. Things could have been much better if I had not got the injuries or if I’d played more games.
“But when I look at my statistics and those of others who play in my position and had more game-time than me, I don’t have to envy anyone.”
His claims comes despite just nine goals in nearly 50 games for the Hammers.
Although his brace in the memorable 3-2 comeback win over bitter rivals Tottenham at Wembley endeared him to supporters, the truth is Ayew will be quickly forgotten in East London.
Whether it was a case of being regularly played out of position or simply not getting enough consecutive game time to find his form, things just never clicked for the African in a Hammers shirt.
Indeed he will be remembered more for his infuriating tendency to half-heartedly close down opposition defenders, often rendering any game plan to implement a high press futile.
Ayew would also spend most of his time on the pitch pointing at his teammates and throwing his hands up in the air in a petulant fashion, something that grated on fans.
Now his comments prove West Ham were right to move him on and the club must be more efficient themselves when it comes to bringing in players to improve the team going forward.
