Totally agree. Think having an LB the quality of Leighton Baines and then managing to find a replacement the quality of Digne has made us all complacent. It is incredibly rare to find full backs of that quality. Particularly when we are, for now at least, regrettably a mid-table club.
This lad may be the dog's-you-know-whats, but we shouldn't look to shift any of our top players (of which there are very few) unless we absolutely have to! We should be building a team around our better players for now. If we move forward, we can sell some of them to reinvest, but at the moment we run the risk of going further backward if we sell the few good players we have.
On the other hand, if we have way more money to spend than we thought, and we are bringing in quality competition, I am all for it!!
