Dyer is set to join West Ham, after the two clubs agreed on a fee for the former Ipswich winger.
Big Sam said: “My job now is to replace him, which shouldn’t take too long I don’t think, and then move on to other players in other positions as quickly as I can or at the same time.
“I think we’ll be close by the end of the week to maybe one or two players, I would hope.
“Then after that I would look to get at least another two or maybe three in because if Kieron goes, whoever comes in to replace him, that’s only one for one, so it’s not actually improving the squad in terms of strength in depth.
“There’s still three or four players need to be got on top of whoever we replace Kieron with.”
