After Lingard's most terrible run of games in his Manchester United career... I think the biggest proof is Rashford just keeps doing bad decisions, selfish shooting from impossible angle, ignoring teammates, wasting freekicks time and time yet does not step down despite we have better freekick takers in the team (Pogba and Mata). Just like how Pogba keeps being given penalties although he had a low conversion rate of penalties (Only Rashford can take it from him, mind you). So far I have not seen any proofs that Ole can probably tell them off, to either cut off those unnecessary antics (Particularly Rashford's wastefullness and being selfish, ignoring teammates...) or get dropped. I think he needs to be more ruthless and intimidating.
