He used to make those intelligent late runs into the box a few years ago but has been playing much deeper for Ralph. I'd love to see him move forward and take a few potshots too.
It looks more like a 3-4-2-1 to me but with Aribo and Armstrong both given full license to push forward. I'm a big fan of it so far, and will be for as long as the players don't let it turn into a 5-4-1
Here's a nice stream if you don't mind for the Spanish commentary. https://poscitech.com/southampton-vs-villarreal/?sport=soccer
Definitely looks like a 3-4-1-2 in possession. Trying to get Aribo up in behind the front two of Mara and Stu.
