Love Mandzukic, but statistical comparisons to Costa at this point don't say a whole lot. Costa's stats are basically just hinting at what his potential productivity could be.
DC has new teammates to get used to, has played both sides, and Max has also used him sporadically. Obviously not a terrible number of minutes, given he's a new arrival coming into a CL finalist squad, but obviously not much continuity over the first few months of the season. Mario needs to be more engaged than he has been lately, and hopefully he's totally focused against Tottenham -- going to need him. Definitely more inconsistent performances from him this season, and 32 in May. Love what he's given us over the years, but doubt he's going to be locking down that left flank for very much longer.
