I agree with most of that. Going forward out of the ones you mentioned i would keep Buendier and think he could be a top player with better players around him. Yes Digne and Courtinho were very good signings. I would sell ings and Bailey for sure and invest in a top quality forward that will really get us excited. Nothing against Ings but hes a mid table player imo.
Love him or hate him i think Suarez will be here within a few weeks.
