I think that you can "carry over" two transfers from one day to the next. This would, if I am correct, give you four transfers tonight. I think that you need to be very very careful not to score hundreds more points than I do!
Also, it is important to remember that after clicking on "Make Transfers" the first time, it takes you to another page where you need to "Confirm Transfers". The website tells you this, but it is very easy for a Director Sportif to miss this instruction. It was not me, and I will not mention who did it.
