I fully agree, no player should be promised or assured of anything. Except maybe back up keeper, he's never going to displace Hadt, so he needs an incentive to be ready.
I don't agree with it, I just understand it..
He has never struck me as a manager who promises a player anything as far a an automatic selection in the team not withstanding he has a player pecking order when they are available for selection.
eg He won't start Nacho at Kun's expense , nor leave Yaya out even if all mid fielders were available for selection.
As many have said he believes in Yaya as a player who can pass with the greatest degree of accuracy and speed of release ( not sure if the stats back this up ) and the player who he most relies upon along with Kun to score a goal no matter the scoreline or situation.
I rate him as a reasonable man manager but I don't rate him all that highly as manager who can get the best result in the most number of games possible.
We just concede too many goals in too many matches to be too less competitive than we would be under a better results driven manager.
We have conceded 2 goals or more some 49 times under MP , and I am sure if we looked at the w-d-l on those games it would not read well.
