And the Lionesses chief wants Fifa and Uefa to sort out match scheduling and congestion issues so players can “stay fit and fresh”.

England are among the sides who have played in successive tournaments over the past three summers.
And it’s led to WSL stars and players from domestic leagues having shorter breaks ahead of the start of new domestic seasons.
Wiegman said: “What the players want and what they ask all the time too is ‘where is the rest for us?’, because they want to compete.
“We want the players to be fit and fresh.
“This means that you always need a proper rest, but you also need to train between June and July too.
“We’ve had some conversations with clubs, and these have been good conversations,

“I’ve spoken to her, and I hope she has more consistency there. I have gone with other players but it was a tough decision.”
