For the first time since the 2005-06 season, Edwin Van Der Sar will not be the starting goalkeeper for Man Utd.
His retirement spells the end of an era that saw Van Der Sar backstop "The Red Devils" to four Premier League titles, a FIFA Club World Cup, three FA Community Shields and the 2007-08 UEFA Champions League title.
This spells the beginning of David De Gea's career with United. Previously, a member of Atletico Madrid of La Liga, De Gea established himself as a top young goaltender in Europe.
De Gea was highly sought after and with him in net for Man Utd, they have a 20-year-old that could be their future on the back end but for the immediate future, will it be Man Utd's Achilles heel?
The pressure of success can get to plenty of players and for some, it takes at least a year for elite players to get used to a team dynamic before their success helps the team get better.
Case in point, Wayne Rooney. When he came over in 2005, Man Utd finished in third for the second straight year. Since then, they haven't finished out of the top two.
It's a process and as the last line of defense for a high profile squad, the young De Gea will struggle in his debut season, which will lead to struggles for the entire team to achieve league title No. 20.
