Barcelona: Netherlands legend Johan Cruyff believes that both Barcelona and Manchester United have the ability to win the Champions League final in London later this month.Barca and United will confront each other in the final of Europeâs premier club competition for the second time in three years at Wembley on May 28. The two teams locked horns at the Olimpico in Rome in 2008-09 and at the time the Spanish champions ran out comfortable 2-0 winners.Both teams are seeking to win the European Cup for the fourth time in their history, each having won their first at the old Wembley stadium. Barca are being considered favourites by a majority of the footballing contingent but Cruyff believes that nothing can be taken for granted at the moment."It is a one-off match, so anything can happen,â the Dutchman told Catalan daily Sport.Cruyff, a legend at Barcelona both as a player and as a coach, was at the helm when the Catalan giants won the tournament in 1991-92 and believes that just like his team, Pep Guardiolaâs side are âperfect.â"They are doing pretty well,â he said. âThe aim is to always try to assemble the best team possible, to play good football and to ensure that young people are proud to be associated with the Blaugrana. Comparing these things isn't really the best approach."When we won it, we were perfect. When [Frank] Rijkaard took over, they were perfect again. Now under Guardiola's system, it also seems perfect for Barcelona. The most important thing is that Barcelona are proud and happy with what happens on the field."Barcelona are also on the verge of wrapping up the Primera Division title as they are eight points clear at the top of the table with just four more rounds of matches left in the championship this season.
