Manchester United manager Sir Alex Ferguson has admitted Barcelona have improved since their last meeting in 2009, ahead of Saturday's Champions League final.
Yet the Red Devils boss insisted players like Lionel Messi can be stopped, highlighting the strengths of his own title-winning squad.
Pep Guardiola's side defeated Manchester United 2-0 in the 2009 final in Rome, when a Messi header sealed victory and European glory for the Catalan club.
Ferguson also confirmed this week that United are close to completing a deal for Atletico Madrid goalkeeper David de Gea, which will see him move to Old Trafford for £17million.
Speaking of the 20-year-old stopper, Ferguson said, "he is young, very quick, with good composure and is an outstanding replacement for Van Der Sar."
In preparation for Saturday's Wembley showdown, Manchester United's famed 'Class of 92' were reunited last night for Gary Neville's testimonial game against Juventus at Old Trafford.
Ryan Giggs, Nicky Butt, Phil Neville, Paul Scholes and David Beckham played alongside Neville, with 3,323 United appearances between them, to celebrate the end of the one-club defensive stalwarts illustrious career.
