I have started using an attacking formation using inverted wing backs, currently with Chelsea just at the end of the second season, problem is there dont seem to be many players around who are inverted wing backs, can anyone recommend any decent ones
There aren't many. What you'll need to do is prioritise the key stats for your playstyle and re-train players. This will depend on your formation as the IWB will behave differently if there is a player directly in front of them (MR, ML) or depending on their mentality. From scouring the internet people seem to suggest re-training a DM is the best bet, as they typically already possess most of the key the stats (Decisions, Tackling, Positioning, Passing, Dribbling, Work Rate, Pace, Stamina).
