Basically the nowaday wingers that don't cut it at their role usually end up as full-backs. It's a position that has sort of risen.
I mean dudes like Aleix Vidal (actually played as a winger though), Kyle Walker, Clyne etc... Back in the day they would've probably ended up as wide midfielders, but since the lack of their ability when it comes to technical play in the opponents' last third they've got not much choice.
Just a thing I wanted to point out when it comes to evolution in football in tactical and positional terms over time.
But some teams are still playing 4-4-2, 4-4-1-1 or 4-2-2-2 however you want to perceive it. Atlético Madrid and Villarreal for example are doing very well.
It's quite simple really, one of the strikers has to be a quality finisher. Another one willing to track back and almost act as a playmaker (#10) at times, also being able to score.
You can opt for either two nowaday wingers or just AM's on the wings. Remember that the nowaday #10
has changed so much. Players have become much more versatile, and most of the quality playmakers these days can function on the flanks and in the centre (De Bruyne, James, Özil, Isco, David Silva etc you know all of them). To think of it, I can hardly come up with some world class #10 who's only limited to playing in the middle of the park. They're are a dying breed, same with poachers. Managers expect so much more from the strikers when it comes to build-up play etc.
I can recall watching Villarreal against Celta Vigo during the weekend perfectly for example. Having two strikers can be a real plus especially when one of them is making a run at the right time. Roberto Soriano (LM) scored after a perfect pass from Castillejo (RM)
with the defenders being busy marking the strikers etc. So basically if you've got the right players and quality central-midfielders it's no way a "dead formation".
Leicester won the Premiership in a similar fashion last season for example.
Atlético for example are a curious case though, they've got loads of depth and so many players who fit their system and play in multiple positions (both Koke & Saul DM, CM and on the flanks for instance). The likes of Griezmann and Angel Correa as a supporting striker, on the wing or completely at the top etc... Plaudits also go to El Cholo.
You need the team to perform as a unit to pull it off basically. The game has become much more technical as the years have gone by, and I suppose this is the best example of the nowaday 442.
And anyway the formation changes a lot during different stages of the match, when a team is defending or attacking etc. Depending on the scoreline and so on.
What I like about Atlético so much and Simeone's system is that they can easily change it to a 4-3-3 when attacking, 4-1-4-1/4-2-3-1 when defending etc without really having to play their players out of their preferred positions.
Koke - have to bring him out especially, what a player.. Essential to Atleti's playstyle. Can play anywhere, further back, between the lines as a playmaker, on both flanks. Irrepeplacable (sp). Saul is similar.
Sorry if this came out too long, it's basics, self-explanatory (for those who've been following football with enthusiasm) and most of you know it all anyway. Just got carried away is all. There are so many people who just watch the ball during a match and don't follow anything else that's going on around the field (players' movement, positioning etc).
TL;DR - 4-4-2 still works and a top four team in the World is going by it heh..
