Which is a free weekend as Man United are away at Spurs, as mentioned earlier I think the game has to use Old Trafford as first choice or risk souring a good relationship there.
As for players contracts, I believe the the 'last registratio' date would move back, so new players can't play and short term agreements made for players to play for their current clubs. This happened in Football last summer.
