The trouble is people just see Heitinga (a centre back by trade) coming on for Jelavic (a striker) and just assume it's a negative substitution taking off a striker and throwing on an extra defender.
The reality though is quite different isn't it? Fellaini was playing today as a holding midfield player with both Anichebe and Jelavic up top in a 4-4-2. Jelavic was once again totally ineffective today so a change was made.
Heitinga didn't come on and join Jags and Distin at the back to shut up shop, he slotted in to Fellaini's holding midfield role where let's be honest, Fellaini didn't excell today. Heitinga CAN play a holding midfield role and you'd trust him more there at the moment than centre half!
Fellaini was then pushed up in to a role hes been excellent in this season, to join Anichebe and hopefully prove to be more effective than Jelavic who might as well have stayed at home today.
But no, in the eyes of some people who don't understand football, the ginger **** just took off a striker and replaced him with a centre back!!
