Till it’s signed (which it wont be) everything stays an option I reckon.
The interview I posted with Moyes in another thread the other day, he’s said he was offered a contract at WH but it was withdrawn before the end of the season after a few bad results. Goes on to say he wasn’t happy about it, but it will have been for more than he’s getting atm.
Earliest DCL can contractually secure anything will be the next window and then only with a foreign team iirc.
