Arsenal midfielder Andrey Arshavin believes that Sir Alex Ferguson is the main reason behind Manchester United's continued success in all competitions.
Ferguson is in his 25th year as manager of the Red Devils, having just won his 12th Premier League title to overtake Liverpool's overall haul of 18 with the club's 19th top-flight trophy.
The Scot shows no sign of calling it a day despite having become the most decorated manager in the club's history, and appears to be building another strong side with the additions of David de Gea, Ashley Young and Phil Jones.
Arshavin has yet to taste any success with the Gunners since joining from Zenit St Petersburg in 2009, with United taking home two league titles since his arrival.
The Russian, who has been linked with a move away this summer and is reported to be a target for Galatasaray, told Sport-Express: "First of all you have to ask Alex Ferguson about the secret of the victories.
"I think Manchester United have everything (to win) for 20 years - the players' quality, the team spirit and the psychology of winning.
"In the team one can discover the mixture of young and seasoned players and also Alex Ferguson's strictness in how he builds his team as he thinks it's important."
