I would go with Murray.
The scottish has a more regular game that Roger can suffer a lot. Not randomly Andy leads head to head 9-6.
Yesterday Roger got rhytm by Del Potro's linear and strong shots, but Murray has many more variations and if he uses them well he can break Roger's game and make him to provocate many unforced errors.
Another consideration: in 15 matches Fed defeated Murray on hard outdoor court just two times; the other wins of the swiss came on indoor, where is easier to go with one-two shots schemes and make rallies shorter that is what Roger has to do with Murray.
Another aspect I noticed since the first point with Djoko is that Murray's first serve is very solid and if a motivation to pick Roger is that he's serving so good, we can say Murray can do the same today if will put many firsts in.
Dubai's surface is not so fast and that's another point in favour of Andy.
I'll probably pick him.
