8 in no way is a lot for us mate.
Just to put into context
24/25 - 8 players in
23/24 - 5 players in
22/23 - 8 players in
21/22 - 8 players in
20/21 - 7 players in
19/20 - 8 players in
18/19 - 6 players in
17/18 - 12 players in
16/17 - 8 players in
15/16 - 7 players in
14/15 - 9 players in
13/14 - 9 players in
That's pretty much averaging out at 8 players a season over a period of 12 seasons time.
That pretty much takes us from up to when Moyes left.
A few of Moyes more active years to show context of why maybe he's fine with a large amount of incoming players at once.
07/08 - 11 players in
05/06 - 11 players in
So the season after Rooney left Moyes did a massive rebuild, followed 2 seasons later by another one.
People often throw out the 9-10 players is way too much we will never do that, in fact we had e on multiple occasions.
