Ryan Giggs likes the American way of life but has played down the prospect of ending his remarkable career in Major League Soccer. Manchester United's record appearance holder, heading into his 18th season at Old Trafford, is building up his fitness at the club's training camp in Chicago.

Such is the esteem he is held in, Giggs managed at the age of 36 to secure a one-year extension to his contract, and the one-club man is expected to finish his career where it began in the 1991/92 season.

Asked in a phone interview posted on USA Today's website about the possibility of playing in MLS, Giggs said: "Being in America you have a great lifestyle, good for raising a family. The play is getting better. I still have a year left with Manchester United. After that maybe, maybe I will be too old."

United take on Celtic in Toronto on Friday before further tour matches against Philadelphia Union, Kansas City Wizards, the MLS All-Stars and Chivas Guadalajara.

Giggs, who has made 838 appearances for United, scoring 155 goals, knows the team faces some stern tests in the coming weeks. He said: "MLS has grown and the success of the USA in the World Cup can only have helped football. We want to get our fitness. It is a good opportunity to get our rhythm against good competition."
