I personally think the Chelsea game will be the Saturday, especially with the Villarreal game on the Tuesday and also Chelsea play Juventus that same night as well. If either or both those games were on the Wednesday then no doubt it would be moved to the Sunday. The Arsenal game I think most likely will remain on the Tuesday night, especially for tv broadcasting purposes. Looking at the fixture card that week, that’s the only midweek fixture that has a 8pm kickoff time whilst the others all have 7.45pm listed. Probably it’s already been provisionally agreed that will be the date and kickoff time for that game but it just hasn’t been officially announced yet until they confirm the rest of the games for that midweek fixture card? They will probably shift the Scouse derby to the Wednesday night as no doubt Liverpool will be playing on the Sunday due to playing Porto in the CL on the Wednesday.
Having said all that, I guess we just need to wait and see. Hopefully gets confirmed soon as I’ve got both match tickets and hotel booked for the Arsenal game
