I think the point is that The FA have introduced a 'mid season' break, where all teams will have the same time off, although staggered so not at the same time. The FA have then written to clubs asking that they respect the break, and not to schedule any friendlies etc during that time, as the break is designed to benefit the players and clubs by allowing some time off. They then schedule FA cup replays during the break..... It is farcical. Liverpool have the squad capable to field a team for the replay, and so do most other teams in the PL, but what is the point in having a break, if the FA are scheduling games during it? If the same applied to City, I would hope Pep and the club made a similar point of saying they were not going to be at the game, and field the kids as well. It is not just Liverpool in this position though, and clubs like Spurs and Southampton may well field strong teams in their replay, but they shouldn't even have to make the decision, as they shouldn't have a break that isn't totally free from possible fixtures.
As for staggering the break, just give everyone the same 2 weeks off and stop pandering to broadcasters. Would 2 weeks in January or February without any games featuring a PL team be such a terrible thing? The same amount of games would be broadcast throughout the season anyway.
But it isn't the FA that have introduce the mid season break, it's the Premier League and as usual the two organisations seems incapable of collaborating in the best interest of the game. It's ridiculous that it was even ever an option that replays would have to be played in the 'break'. -
