You can legislate for it - you buy another striker that replaces him when injured
If we had just finished top 7 with a good squad I would agree but the reality was prior to DCL's injury we needed to sign:
2x CM's
2x wide players
2x CB's
At the minimum - thats 6 players with our limited budget due to FFP.
Its easy to say we needed another striker but strikers cost the most money and if it meant signing 5-6 players to strengthen the first team or sign 1 back up striker to DCL the club made the right decision.
We need a CF but for me a top quality one to replace DCL and that was never a possibility this summer with our budget constraints and the sheer number of bodies that we needed to sign to strengthen this awful squad of ours.
