Arsenal hero Paul Merson has slammed Manchester United's swoop for free agent Edinson Cavani.
The former Paris Saint-Germain striker, 33, signed as a free agent on deadline day to bolster the Red Devils' attack.
Merson wrote in the Daily Star: "Edinson Cavani is an underwhelming signing for Manchester United that shows they are going nowhere.
"He's been available on a free transfer since I don't know when, and I don't think they got beaten by Tottenham because they can't put the ball in the net.
"Having a man sent off in that game just gave them an excuse. They were already all over the shop defensively.
"It's hard to play for a big club when you haven't got any pace and their centre-backs have none.
"I thought they were a shoe-in for the top four before the season started but until they get some legs in that back four I don't see where they are going.
"They have opened the door for teams like Arsenal, Tottenham and Everton to finish in the top four this season."
