Pallister told the Daily Star: "They were chasing Fabregas and there was talk about a late bid for Gareth Bale.
"They're the kind of signings that really stoke the fans up as well as the players.
"Fellaini's a good buy but I still think we're lacking a creative midfielder.
"It's a position David Moyes needs and he will be trying again. United need a player that gives you a different dimension in there.
"I'm sure there will be one or two new signings in January - I think they might go back in for Herrera."
