Whilst it's a lot of money for him there was a lot of people moaning about the weakness of our options last season if Costa got injured. We had Remy and Pato to turn too, if this happens that Morata arrives, we have signed Mitsy and bring in say Pelle we then look immediately stronger as a whole. For me and one of our downfalls has always been the thinness of our squad if we suffered injuries/suspensions to our key players and the lack of quality to fill a void.
Losing Costa would be a blow, but if we purchase Morata plus another option like I mentioned we are very well set to have great striking options.
