The doubts over the mental strength is understandable
KDB wanted to start despite not being good enough. His justification ... Oh I stay late after training and stopped drinking Coke and eating chocolate, yet Jose doesn't start me. I am off bye bye
He wouldn't have been a regular. Schurrle, Willian and Oscar all better than him
On Lukaku ... He ran off on loan when Eto'o came. He didn't want competition. Costa embraced competition when Falcao came. He was sent on loan numerous times yet didn't moan about it
Costa was out on loan when Falcao signed. So all this arguments are based on incorrect data.
