Team is as under.

The following are the planned substitutions:
Sturridge Out: Rooney In (Yes, I am rich)
Walters Out: Chamberlein In
Vorm Out: Lindegaard In
Dawson Out: Best of the rest In (Looking at Fulham / Stoke defenders; or Coloccini / Santon/ Raylor --- What's the Cahill Chelsea scenario?)

I can afford all of the 4 substitutions- what do you suggest should be the order?
FTM, is there any substitution that you suggest I don't do, from the above?

Wildcard taken last week.

I don't agree with Sturridge. I think he is a quality player, we have seen what he can do and he can do it again over the remainder of the season. He is 100% to start games when fit and 7.5 is a snip (IMO). Rooney doesn't look like scoring of late, he is playing a lot deeper than usual aswell.

For Man Utd coverage I would go with Valencia.... 8.1 can't be argued with for a player of his quality. We have allready seen he can score points against top teams, he can score points from RB, he plays every single match and creates chances every game. I think he is a better option than Chamberlain(had a good game) because Valencia is tried and tested and plays for a better side... On top of that... who knows what goes on in Wengers mind! he will probally continue to sub him off for Arshasvin

I think you should do:

Walters out: Valencia In

Not sure what comes next.. I agree with the Lindegaard transfer.

With the surplus money you could go for Dawson Kompany/Cahill?

Agree with bolded parts plus;
If you don't want Sturridge, get Bellamy or Welback as place holders until Ba returns.
Get Lindegaard and Valencia in, they are the two best - highest VFM - United players.
Enrique+Dawson+Clichy (OUT) (IN) Huth/Shawcross+BAE+Richards
If money still there... get a Fulham midfielder, preferably Dempsey or even Duff/Murphy for McClean.
