I imagine the plan is we will play him if another club doesn't come in before the window closes.
If there is a plan to bring in a quality player with the money spared then we should look to move him on. That's a big if though I guess.
Would need to know what our finances are like in regard to FFP to have a proper opinion. If the calculation for FFP is spread over three years, I would rather we didn't waste money this year as I feel we will neither go up or down.
