With the influx of players and managers from other leagues, the style of the English game, at least at the club level has changed significantly. Players like Jones etc will have to work even harder now to score in environments where teams are playing the ball more on teh carpet than they are relying on aerial dominance. Clubs like Arsenal, Chelsea, Liverpool etc all play a style of football that rely less on big players and aerial dominance in attack.
Adebayor stands over 6ft 4, yet he rarely scores headed goals.
There are quite a few teams in the Premiership that plays the old style long ball, areial game which benefits players like Jones. Sunderland comes accross as one of those teams. Bolton and Wigan are other examples. These are typically the side that have a predominantly large pool of English players (playesr who have not played in other leauges outside England). And 80% of the teams in the championship didvision play this type of game as well.
