I'm honestly not that bothered about this competition having won it last season but I'm always glad to see us go through and this helps to put us in a more positive frame of mind before the Spurs game. A lot of key players got rest (though IMO bringing Lukaku and Matic into the game for 20 minutes was needless) and we saw some encouraging play from McTominay and Tuanzebe.
Some nice work by the front 3 of Martial, Rashford, and Lingard. Lingard probably had his best game in the first team for us. I always felt we have the long-term potential for a really effective, free-playing 3 rather than using a lone striker like Lukaku or Ibra who can too easily get snuffed out of the game. Allowing Martial and/or Rashford to switch sides and giving Lingard a free role kept Swansea guessing, it's something that having one man up top can't provide.
Herrera and McTominay worked well together in MF. I thought Herrera was much more positive with his ball movement. He has the ability to play an effective ball forward but he's been in a more defensive role since last season and has looked too similar to Matic when played together. Because of the opposition tonight he showed more ambition and got the move started on our first goal. McTominay was efficient - nothing brilliant, just steady as Herrera's support, did nothing wrong.
I won't lie, I am really concerned about our defence. Swansea hardly ever got into our box but our backline seemed to unravel every time they managed to do that. It seemed that we weren't marking properly, no one was able to clear balls with any authority (Blind's header off a Swansea player that nearly resulted in a goal comes to mind), and we looked very susceptible to movers like Ayew.
I know that the defensive setup had players who hadn't been together much this season but we didn't look organized that well. I think Smalling, Darmian, and Tuanzebe had good moments as individuals. Lindelof, though, was again terrible and looked like he doesn't belong anywhere near the first team. If I have to watch him against Spurs, I'll need to be carried from my television set. Blind, meanwhile, was not bad per se but he clearly struggles in the wingback role against PL teams.
On another note, Sky Sports needs to quit using poses when display the starting lineup. I was laughing at our squad when they showed half of them looking gangsta and felt terrible in doing it. Tonight's performance gets a 6 out of 10.
