We bought two more right sided attackers (Buendia, Bailey) when we lost a left sided attacker, who was also our best player. The madness was two fold in overstocking the right side of attack while completely neglecting the left, so I think we did need to buy more attackers...we just bought them in the wrong position. Maybe three fold when Ings is included...prioritising another striker over our biggest glaring gap. It's a mistake that cost Smith his job and has the club wasting millions on superfluous players.
(Admittedly Traore and Bailey have been injured a lot, so clearly some depth on the right has been necessary!)
