Man United are unbeaten in their last five Premier League games ahead of the November international break.
Amorim’s side will hope the break hasn’t ended their momentum as they prepare to host Everton on November 24th.
Sir Alex, who is the last Man United manager to win a Premier League title, does see cause for optimism, largely due to the addition on Lammens, 23.
“There are signs, the manager has had some good signs,” Ferguson told Raceday RTV.
“Particularly the goalkeeper has been outstanding, he’s only played three or four games and he’s looking really good.
“Of course, Mbeumo and Cunha, the new players from Wolves and Brentford, they’ve added to it.
“I hope the manager gets a bit of success because at United you need to have success - the signs are getting better.
“I think back-to-back wins is something teams like United should always expect. But having gone through a cycle where the improvement has to come by waiting and being patient, they’ll enjoy it now.”
