Liverpool legend Graeme Souness believes fourth place is a shootout between Manchester United and Chelsea.
Souness has dismissed Arsenal as a top four contender.
"It's a straight fight between Chelsea and Manchester United for fourth now," Souness told the Sunday Times.
"But Chelsea will be looking over their shoulders because United are dangerous and, right now, the momentum is there with them and they are on a roll.
"Chelsea will win more games with Higuain scoring goals for them, but we will have to wait and see if he can take them to fourth place."
