The Hammers invested around £170m on a raft of big name additions at the end of last season including Italy and Brazil internationals in form of Gianluca Scamacca and Lucas Paqueta.
For much of the campaign, the heavy spending did not pay off as Moyes’s side struggled to scale previous heights in the Premier League.
Still, with safety now all-but secured, attentions have now turned to the Europa Conference League.
Thursday night’s comeback win over AZ Alkmaar puts the Irons in command of the semi-final ahead of next month’s showpiece showdown in Prague.
As is stands, the club are on course to win a first European trophy since the team of 1964/65 lifted the UEFA Cup Winners’ Cup against 1860 Munich.
With the hope that the signings made last summer will offer an improvement next time out, Moyes said: “For the most part of the planning is put on the back burner until you have kept your Premier League status.
“The truth is the only focus has been on staying in the Premier League.
“We have brought in a big number of players last summer so I see [this summer] more as tinkering and bits and pieces being done here and there. I see a change here or there and an addition or two.”
