Whether it works or not seems to depend if you've made a change already. I have four teams, I made subs and transfers alright in three of them but in the 4th one I'd already made a transfer earlier in the week which I am now stuck with.
If I try and make any additional transfer, including reversing the earlier transfer, nothing works. I was planning on cancelling that one and going with Fernandes instead but that's a write off so expect a big haul from him over the next few weeks
Why rush through changes to the website just before a deadline?! There's another International break in a week why not do it then? So annoying.
