I tend to agree with this argument up to a point.

It's a gimme that Paterson is hardworking but not a natural centre forward. Perhaps he also could do with a bit of a rest.
So I reckon if Danny Ward is as fit as Pato, either he or Glatzel should start the game against Blackburn but we play a similar way same winning formula that is to say same shape and on the break, like the "away side".
We would still have the fresher centre forward option off the bench.

Blackburn need to win the game and It's unlikely they'll set up as Charlton did. There should be gaps for us to exploit with a striker who can exploit them.
