Similar case last season, did they actually need Jones and Young? whom they spent ridiculous money on, sometimes you've got to question Fergie's transfer dealings. He's improving the squad at the expense of the first team.
Jones we will only know whether or not he was a good signing when he's in his early to mid twenties, he's not even 20 yet and early stages of last season he was epic so signs were good he'll become a top class CB
Young.... no we didn't need him, he hasn't improved the starting XI and if it weren't for the fact he can score really good goals he'd barely of improved the squad
