The footballing legend tries to pinpoint where the Gunners boss has gone wrong...
Wenger has become famous for having complete trust in his young and upcoming stars, and in the past has preferred to make stars rather than buy them.
The discovery of players such as Thierry Henry, Patrick Vieira, Kolo Toure, Gael Clichy and Francesc Fabregas are typical examples of players who were generally unknown or had hit bad times at their previous clubs who found their way under Wenger.
Arsenal reached the League Cup final in 2007 using the youth of their squad, and Robson believes that Wenger's decision to stick with this line-up for the vital final was the wrong choice.
Speaking to Northampton Chronicle and Echo, Robson said, "It will be fascinating to see the line ups in today's Carling Cup final.
"Two years ago, I said Arsene Wenger should name his strongest side for the final against Chelsea, even though he had used his kids to get there.
"The reason was Arsenal needed a trophy. Wenger ignored my advice and Arsenal lost.
"Now he is coming under pressure because the club have not won anything for three seasons."
Manchester United take on Tottenham Hotspur in today's League Cup final, and Spurs will be hoping they can hold onto the trophy after beating Chelsea to win it last year.
