Not having a pop at you here Ian (honest Guv!) but when someone quotes a source as saying "will" rather than "might" is that just a case of being loose with the English language or are they actually that sure about it?
For example, if someone 'inside the club' had got wind of the fact that a player was booked in for a medical Wednesday this week, that doesn't mean they "will" sign for us but it might lead to the source articulating it as such.
So, just to clarify, is your source adamant that they "will" sign or is it more of a "strong possibility"....?
cheers!
