If Mata leaves, he could be Oscar's backup. Seeing that we will struggle when Lampard, Terry and Cole are leaving with the homegrown quota, we should bring him back asap to be club trained. We don't need to have 11 world class starters + 11 world class backups, the club trained youth is the key when they are good enough like Piazon (Moses is homegrown btw) Is Kakuta club trained or homegrown? If KDB and Mata are off, that would gives : Schuurle - Piazon - Moses (+ Kakuta) as backup Hazard - Oscar - Willian as starters And when Boga, Traoré, Mushonda will be ready, we would have greater backups while they are developing with the first team.
