I tend to agree, despite leaving him out of 'my' starting 11. Whilst that sounds contradictory, my reasoning is that I believe JRod needs and/or deserves more game time and the only obvious swap is for Tadic.
I guess this 'dilemma' simply underlines that we have more strength in depth this season, which obviously isn't a bad thing. FWIW, I fully expect Koeman to start with Tadic over JRod, and he's probably a smidgen better at this football management malarkey than me
