Question: Who is the agent for the player with the highest number of appearances in the Premier League?

<P0-S0> The following is a list of clubs who have played in the Premier League since its formation in 1992 to the current season. <P0-S1>  All statistics here refer to time in the Premier League only, with the exception of 'Most Recent Finish' (which refers to all levels of play) and 'Last Promotion' (which refers to the club's last promotion from the second tier of English football). <P0-S2>  For the 'Top Scorer' column, those in bold still play in the Premier League for the club shown. <P0-S3>  Premier League teams playing in the 2016–17 season are indicated in bold, while founding members of the Premier League are shown in "italics". <P0-S4>  If the longest spell is the current spell, this is shown in bold, and if the highest finish is that of the most recent season, then this is also shown in bold. <SEP> <P1-S0> The Homegrown Player Rule has been an initiative in England and the Premier League to allow for more domestic, English players to be a brought up from a younger age in hopes of creating more talented English players. <P1-S1>  Currently, the Premier League does not have a maximum restriction on the number of foreign players allowed on a team, but does require at least eight homegrown players. <P1-S2>  Greg Dyke, new chairman of the Football Association (FA), wants to implement much stronger regulation of foreign players. <P1-S3>  His intention is clear as stated in an op-ed piece so that England can win the 2022 World Cup in Qatar. <P1-S4>  Some of Dyke’s propositions include: homegrown players in a top-flight 25-man first-team squad be increased from eight to 12 two of which must be brought up in the teams youth system, and also changing the definition of what it is to be a homegrown player. <P1-S5>  Currently, to be classified as homegrown one must be on an English team for at least three years before the age of twenty-one in which Dyke would like to reduce to eighteen years. <P1-S6>  This would mean a teenager would have to be with the club at a maximum age of fifteen and players are not allowed to move across national boundaries, even European Union boundaries, before 16. <P1-S7>  Meaning such that, if a foreign player joined an English youth academy at sixteen, in three years time he would be nineteen. <P1-S8>  Thus said player failing to qualify as a homegrown player due to the fact he would be older than eighteen. <P1-S9>  This has become such a hot topic is because there are currently a group of players who have played 309 international games between them but none of them for England. <P1-S10>  While there is currently a list of foreign players, to show the disparity of homegrown players versus foreign players on any given team, the below picture will illustrate such ideas, SkySports hosts an image detailing the number of homegrown players in each Premier League team. <P1-S11>  With an apparent low number of English Players on some teams, especially the larger clubs, this "New York Times" graph in the article further outlines the disparity between table standings if the only goals scored in season counted were those scored by English players. <SEP> <P2-S0> Gareth Barry (born 23 February 1981) is an English professional footballer who plays as a midfielder for West Bromwich Albion. <P2-S1>  He is the player with the highest number of appearances in the Premier League. <SEP> <P3-S0> Michael John Standing (born 20 March 1981) is an English former professional footballer who played as a midfielder. <P3-S1>  Since terminating his playing career, Standing has become an agent for former teammate and long-term friend Gareth Barry. <P3-S2>  He has also played part-time for his hometown club, Shoreham.
