Bearing in mind money is no object in the EPL so put that to one side.
If Celtic offered us 2 million in the last few hours of the window, we should accept it cause he helped us win the Scottish then promotion? What if we couldn't get our desired first choice replacement in cause that team wouldn't do business so late in the window? Or we had to fork out more than we budgeted for because buying at this stage of the window involves an added premium?
Had City bothered to bid a week or 2 earlier, Leicester MIGHT have sold. They'll sell in the summer, for around £70M I reckon but he could be the difference in them getting A) higher position in the league so extra £££ and B) Getting European football so they were well within their rights not to sell to the big boys with all the money IMO
