He never had a poor season, he had an injury plagued season which prevented him putting together ay sort of consistent run in the team.
However, he was actually good when he played and despite not getting the bedding in periods SA players new to this league usually require, as we seen with Bernard, the clean sheet stats back up the impact he made.
He's also been excellent for Columbia which has probably enhanced his reputation even more.
With you being prepared to accept £15 million for Mina right now it just reiterates how poor you would be at that role and makes any opinion on what Brands should be doing with regards to sales completely null and void.
It would be absolutely appalling business that I am sure he could do tomorrow, he just wouldn't be so stupid to do so.
