Not as much of a clanger as I made, had Austin a while back and waited a week rather than transferring to Costa (who outscored him), then transferred to Costa a couple of weeks back... literally the next day QPR's match got rearranged for this gameweek, and then Costa got injured!. Was considering going back to Austin but Mourinho seemed to imply he'd be fit for this week so I left him in as a better long-term option I felt.
Transfer I did instead? Bellerin out as he'd been benched past two weeks (of course he scored), Naughton in (got injured, natch)!
Past couple of weeks have been an unmitigated disaster and unsurprisingly knocked off top spot.
