I can't believe I actually read all that, was quite a bit.
I have to say I disagree completley. What you said was true only in parts. Generally in the sense of a majority of the teams throughout the world, what you say doesn't represent the big picture.
There are so many small players in the world who excell and there has been for years. But there has also been a lot of big players who excell. The game football can't have a solo approach to it. If the game was strictly technical we would've seen teams in Brazil excell to be the best in the world, but when they start hitting the Europe stage, they are easily outclassed.
You use the example of Stoke City playing a physical game and implying the "hoofball" tactic. That's an unfair justification as they are the only club in the EPL who really play that way. That's why their style of play is famous in the league.
Now going to your experience in South America. The approach to the game of a lot of those players isn't as sterotyped as you're making it. Look at players like Lucas, Felepe Melo, Adriano, Lucio, Luis Fabiano etc. Not the most technically gifted players and imply a more physical approach to the game yet they've still seen success for the National Team.
As for the type of players you take preference and thinking there needs to be more of an inclusion on them in the UK, there already are and there has been for a long time. Look at Paul Scholes. One of the best passers of the last 20 years. Small player too. But was a key figure to United's success stories. Michael Owen is another example, mainly from his Liverpool days. A small striker, not the strongest foot in the game, but still proved to be the best player in the world at a point of his career. Similar to guys like Defoe, Modric, Lennon, Silva, Walcott, Nasri etc all of which play the type of game you prefer and are successful at doing so in the EPL.
Fact is, when you were a kid and not chosen to play, it probably was because you weren't good enough at the time. If you could pass well, dribble your way past opponents and be a successful playmaker overall, then there is no doubt you would've been chosen to play. Every coach knows how important a player like that is for a midfield. But if a player can't do all of those things successfully and is small and just gets pushed off the ball, then he's not up to standard.
As for the MLS, it's an average league anyway so it can't be compared to the big boys. But the best player in that league is probably Landon Donavon I'm guessing, he's proven to be a top talent who's small and relies on technical skills over physical stature. Another is Dempsey who even though isn't a small player, relies on his technical and playmaking game to be his best player. That's all worked out for the States, so you can't complain about them taking another approach to bringing in different players if those players already exist.
