I think we might miss out on some players who are late in their years and want to enjoy CL football while they still can. I also feel that if it were last year, we'd be screwed because we would be entering a World Cup and players want to play before World Cups, and our gametime will be weakened.
This year I feel that we can afford to play our best side for most of the PL season and the squad will have to sit it out. Many will want to leave because of that more so than the lack of CL football.
