Sheringham believes United are leaving their business too late in the day.
He told the London Evening Standard: "From his point of view, it was a shame he couldn't do his United business earlier because he was involved with Holland at the World Cup.
"It's a problem for him because he didn't get his new players early like Jose Mourinho did at Chelsea so he knew what he was going to work with. I fully expect him to make two new signings before the deadline but whether he signs the ones he really wants remains to be seen."
