Just thought I would add my experience of using this tactic for reference. I started as Man City (with a data update that brought all transfers up to the start of this season, i.e. Tevez, Adebayor etc at Citeh). Before anyone says that this is just easy and not a challenge, I just want to point out that I am not looking for praise on how well I did, just wanted to point out my findings from the first season to help others.
So as I said, due to the data update and the vast sums of money available to City I had a really good team.
