In a statement, the Women's Professional Leagues Limited, which recently took over responsibility of the WSL, said: "Due to the scheduling of Chelsea’s first UWCL group stage game, the BWSL game between Chelsea and Manchester United due to take place on Sunday October 6 has been postponed. We apologise for any inconvenience to fans. In this instance, we have to put player welfare first and we will announce a new date for the fixture in due course. We thank the clubs and Sky Sports for their understanding as we work on a resolution."
In their own statement, Chelsea explained: "In light of the proximity between the two fixtures, the club raised its concerns regarding player welfare with the relevant parties. Numerous discussions have since taken place in an attempt to find an amicable solution to this scheduling conflict between the league and UEFA. Despite our best efforts to seek alternative options which would allow us to play both matches safely, these have been unsuccessful. It is therefore with sincere regret that we are left with no other option than to confirm the postponement of next weekend’s WSL fixture. We are extremely disappointed with the outcome but wish to reiterate that player welfare and the impact on our supporters are of the utmost importance to us."
