They want, they haven´t bought so many players. The main reason that they are after so many players is that they have to have a big and great squad sine they will probably play in the CL.They have to qualify first.
Leeds are no worse nor better than any other premiership teams when it comes to transfers. It´s ordinary to make many inquiries for players even when you are looking to replace just one position, cos most of your bids are likely to be turned down. That´s why they have made bids for both Southgate and Ferdinand. I will bet you, that even if could, they would´t sign more than one of the two.
