West Ham failed with an attempt to sign Amadou Onana this summer from Lille.
The 21-year-old midfielder joined Everton on a €33m deal and started his Premier League career in good form.
Hammers were interested in bringing the Belgian star to London, but Everton offered more money to secure his services.
As Everton host West Ham this weekend, Moyes was asked about Everton’s transfer business this summer and admitted he is a big fan of Onana.
“I think Everton are a bit like us, there’s a rebuild going on and I think Frank (Lampard) is starting to put things together.”
“Obviously they haven’t had as much money to spend as they have in recent seasons. I think they’ve signed some really good players, Conor Coady, James Tarkowski, they’re very good, experienced Premier League players.
“They’ve brought in (Amadou) Onana, who we also liked, so I think they’ve brought in a lot of good players…
“I know myself, we’ve brought in some good players and it takes a bit of time.”
