Minutes played per goal isn't really a great way of judging a player. Iheanacho had an insane minutes per goal at City at one point iirc. Mitro has started for us in the Premier League 22 times and got 5 goals iirc, 1 of those a penalty. He was much better off the bench for us in 2015/16
He's spent basically zero money there and got them midtable every season. It's probably very boring like but can't see anyone doing better unless they start spending. That Irish kid that they booed Mick for subbing tonight because he was doing well wasn't a stand out player for a pretty average League of Ireland team last season. I know some of their fans and they wanted him replaced last season and were astounded when Ipswich came in for him
