I think 38 will be enough, we need to average slightly more than a point a game to achieve this.
Personally I think we need at least 6 more wins and a few draws along the way. It would also help massively if those victories came against the teams around us.
So far we have beaten Newcastle, Villa and Reading at home and QPR away, we need to repeat some of those wins in the return legs and be more clinical at home.
