The English Football League has criticised the "undermining" of the Carabao Cup after it was forced to compromise on the date of Crystal Palace's quarter-final because of fixture congestion. Palace will now face Arsenal in the last eight at Emirates Stadium on Tuesday, 23 December at 20:00 GMT. The other three quarter-finals take place the previous week but the Eagles' commitments in the Uefa Conference League - they host Finnish club KuPS at Selhurst Park on 18 December - has left them with four games in nine days.

Palace host Manchester City on 14 December and are away to Leeds on 21 December, either side of the KuPS game. A statement from the EFL was critical of the "expansion of European cup competitions" which it believes was "implemented without adequate consultation with domestic leagues".

The EFL said it had "shown a willingness to compromise" but scheduling conflicts are "now entirely unavoidable". "To continue making endless concessions only serves to undermine the reputation of the EFL Cup," said the statement. "It also challenges the traditional scheduling of the English football calendar and strength of our domestic game."

Uefa's European calendar now stretches across 10 midweeks, rather than the six of two seasons ago, with the Champions League, Europa League and Conference League each given a standalone week for exposure. It has caused a huge logistical headache, with the third round of the EFL Cup having to be seeded and played across two weeks to keep clubs in the Champions League and Europa League apart.

Palace boss Oliver Glasner said last week it would be "irresponsible" if the club were forced to play two games in three days. The EFL said it shared the "frustration and concern" of managers and players concerning the congested programme which deprived clubs of the "necessary time for preparation" and ability to "field their strongest line-ups" in the EFL Cup.

The Premier League recently blamed the increased number of European fixtures for there being just one game on 26 December in the English top flight. Boxing Day fixtures have been a long-standing tradition in English football but this year the only Premier League game will be Manchester United's home match with Newcastle United (20:00 GMT).
