We definitely have plans for what we would do if we sold Fellaini. The issue is timing. If it happens early we have a full choice of targets and time to be methodical. If it happens late we may have very few, if any, targeted individuals still available (either sold or current team not prepared to deal at the last minute) and very little time to make a call.
Of course, we'd be evaluating other players potentially in e.g. August but that is not the same level of diligence that we'd have around targets who had been top of our radar and possibly being actively tracked for a year or two.
In the meantime it looks like we are proceeding on the assumption of no sales and that is certainly better than letting the uncertainty paralyse us - better Kone and maybe someone like the Barca lad on loan in the squad than no additions at all.
