I think outside capital injection would be pie in the sky, it's a namesake at best. The club being up for sale, it just wouldn't make sense to get financial injection in return for say shares...would just make it harder to sell I'd imagine.
Unless he's conceded defeat in selling, not sure how our books are but perhaps he will give the chairman / director the reigns to raise capital through external loans and other ideas - or spend anything we might already have in the kitty how they see fit. But I really doubt he's going to release control on anything that might detract from his penny pinching exercise.
