Dimitry Seluk has acknowledged Yaya Toure's birthday was marked by Manchester City.
But he claims Toure was disappointed nobody from a senior position at the club wished him happy birthday.
He said: "Of course some players congratulated him (on his birthday) but not the sporting director, not the general director, not the chairman, nobody.
"(The manager?) No, nobody.
"This is the question. If you don't even congratulate the player or send flowers to his wife or mother - these are just small things."
