Big John can make something happen out of nothing, and can give us a bit of unpredictability, which currently, we don't have. I'd plonk him up front with Gabby. We can't risk playing him on his own, because he just doesn't work enough. Get Gabby to do his donkey work, and Big John could have himself a field day...I hope.
I think he's still got plenty to offer this season. He'll go in the summer certainly, but selling him now, with only 2 weeks to find a class striker, would be insanity. Is insanity beyond Houllier? No.
