Still think Brentford have it in them to turn in around. They're a far better team than Bournemouth, as the league table has borne out. If Bournemouth do come up, they will need heavy investment or they'll be straight back down. They're the same squad that got relegated, but older and without all their best players who left (Wilson, Fraser, Ake etc). Brooks still a talent though.
I've said since their charge from February that it's good for the football league for Barnsley to come up and a great story, but as far as squad strength goes, they're probably not too dissimilar a level to Billy Davies' Derby that got the record low points in the league. Their best player will also leave if they don't come up as they probably can't afford the optional fee they agreed without PL money.
