I think him saying 6 wins out of 8 should be enough isn't particularly useful - it almost sends a message out to the players that he thinks we can lose 2, ok lads we can lose a quarter of our remaining games and we'll be ok.
Back in 74-5 when we won the last 8 to get second place and promotion, if we had lost 2 of those last 8 and those 2 were Sunderland and Norwich we wouldn't have gone up.
So which 2 can we afford to lose then? Not Cardiff for certain. If he has to say anything perhaps he should be pointing out the 7 on the trot earlier this season and that he sees no reason we cant go one better with the players we have, blah blah.
