Its not always like that Tomo, first thing that pops to my mind is a situation between Sturridge and Torres last season where the latter was promised to be first choice by Roman Abramovich after Munich (Torres admited it when speaking to spanish press afterwards). Studge knew he had to play like Messi every game to have a chance of starting. So yes, sometimes its not solely about footballing skills but about other things too. This is why I feel sorry for Moses, if he was paid 20M pounds like Schürrle was, he wouldn't have been loaned out. Simple as that.
