Explained: Why Ella Toone & Jess Park were benched for Man Utd's Champions League defeat to Lyon

It wasn't just the absences of Park, in excellent form, and Toone, leading the Women's Super League for assists this season, that left many perplexed. Skinner also named Dominique Janssen, a strong performer at centre-back, to his bench and Julia Zigiotti Olme, who has been excellent since arriving from Bayern Munich in the summer. It was a gamble that didn't pay-off either, with United not really in the game until Skinner brought on all of Park, Toone and Zigiotti at half time. Even then, there wasn't enough time for the Red Devils to turn things around, with them dealt a 3-0 loss.

"You can lose a game against Lyon on set pieces, on physicality, so we had to have balance," Skinner said, explaining his team selection. "We needed to match them physically from the first half, and then always adapt it and change it second half. I felt that, first half, we physically were matching them, especially from set pieces, but we probably didn't get enough pressure on them in moments, so I adapted it half time, got a little bit more ball possession."

Asked what the reactions of players like Toone, Park and Zigiotti was when they were told they weren't starting this big game, Skinner replied: "When they had the reasons and rationale explained, they understood. They don't want to not play but I always explain the reasons. I don't leave any players blind to what the decisions are. That's my job, to make tough decisions."

When asked about Skinner's emphasis on Lyon's physicality, Jonatan Giraldez, head coach of the French giants, said: "For sure, we have top players, technical players, tactical players and also physical players but I don't think that only the physicality has been key. I think as a team, we have done a very good job today."

It wasn't just about what Skinner felt was necessary for this particular match-up, either. United don't have the biggest squad, with many of those on the bench on Wednesday having played a lot of minutes as a result. As such, there was also a touch of loading factored into his selection against Lyon.

"We've got four games in 10 days, so we've got to be able to rotate," he added. "I won't have anyone go, 'Oh, well, you don't rotate', and then you do rotate, and it's not right. You've got to. There's got to be a plan ahead of all of the games."

Skinner has been keen to point out that his squad needs reinforcements in January, after a summer transfer window in which fewer were brought in that he would've liked. "It's nothing to do with the quality in my squad right now. It needs support and it needs numbers of quality," he said on Wednesday, emphasising the need for more depth to compete on four fronts. "I don't want to diminish anything from my squad. I love [the players] and what they do. It's not about replacing them, but it's about trying to grow the team."

While United have already secured a spot in the Champions League league phase play-offs, an automatic qualification spot remains up for grabs, though it is harder for the Red Devils to secure after this defeat. Skinner's side travel to Juventus next week hoping for a win that could sneak them into the top four, but they will need results to go their way elsewhere as well.

United are currently ninth in the UWCL standings, which would leave them unseeded in the play-offs. As it stands, they could be playing Wolfsburg or Arsenal, though that is all likely to change after next week's final games. Creep into the top eight, however, and the Red Devils could get a much more favourable draw, with the likes of Paris FC, OH Leuven and an Atletico Madrid side they beat earlier in the league phase all in the mix.

The positive is that this is just the club's first stage in the Women's Champions League proper and they will be getting out of the league phase. Who they will face in that next round will all be determined next week.
