He developed Arnautovic and Antonio into two of the best strikers in the league. Bowen has come on leaps and bounds, eventually getting an England callup, under Moyes. Kudus has been a shadow of the player he was last season under Moyes.
See article below, which reflects my concerns:
The Hammers have won just 13 times in the 53 games in all competitions since under Moyes, Julen Lopetegui and now Potter.
There are a host of reasons for the downturn.
The biggest is the poor composition of the squad and transfer dealings.
Now Moyes should hang his head in shame after a startling new West Ham striker revelation.
The Scot will hold a special place in Hammers history for what he did in five years over two spells.
But he was not perfect.
Moyes’ insistence on having a small squad meant West Ham were left with the smallest and second oldest squad in the Premier League when he left.
The Scot failed to make good on promises to build the Hammers around young, hungry players.
So West Ham had to spend big money – over £155m – on a rebuild last summer.
That rebuild somehow made the second oldest squad,
the oldest in the top flight.
That has ended up costing Tim Steidten and Lopetegui their jobs.
But it was Moyes’ continual dithering over signing a striker that has set West Ham back more than anything.
Moyes failed West Ham over strikers
It took him over 18 months to replace Sebastien Haller with Gianluca Scamacca.
When that didn’t work out, ageing Danny Ings was brought in as a panic signing.
Moyes then refused to sign a striker in his last summer window, insisting Jarrod Bowen could do the job.
Some of the deals he turned down are still haunting his old club.
Moyes admitted turning down the chance to sign Julian Alvarez from MLS for just £14.5m before he ended up at Man City.
Despite watching Viktor Gyokeres live multiple times and having him on a platter for just £17.5m, Moyes also turned that deal down.
Now West Ham will be absolutely livid with Moyes.
The Hammers face having to sign at least two, if not three, strikers this summer.
But funds are a problem after the club were forced to stretch spending to bolster the 17-man squad the Scot left behind.
