My preference would be OOP, if I'm honest. For Wednesday's league match, I had one of my 3 strikers out injured, and as I play 4-4-2, it meant playing my only 2 available st's. But as the injured player is out for another 3 days, I was hoping for no more mishaps. One of my strikers was on a yellow card and I didn't want to risk a suspension, so after 65 minutes and with a lead of 4-0, I subbed him. With no other backup striker, I sent on my lowest quality DL, to play up front. And he bagged our 5th just before the end. Whether I would have started him there though, is another matter.
