I think it is especially sound given he has the option to fall back on. Unlike others, It's not like he is risking an injury in the meantime jeopardizing his future earnings. Without that option as his manager id be recommending securing your future but with it, it's the most logical play in my opinion.I agree.
900-950 is tops for Bula. I doubt anyone is paying more than that.
Manager has probably advised as you said and also to see how we are going after 5 to 10 rounds.
As a player and given the club history and ownership craziness, it's sound advice.
Trying to strong arm will just end in tears.
