"All you need is love" sung the Beatles in their 1967 release of the same name, and according to Chile coach Reinaldo Rueda, that's what's been missing from Manchester United misfit Alexis Sanchez's game over the last 18 months.
Over three and a half seasons with Arsenal following his ?35 million ($44 million) move from Barcelona -- where he had to make way for the arrival of Uruguay's Luis Suarez from Liverpool -- Sanchez built a reputation as one of the most feared forwards in the Premier League.
He was twice voted Arsenal's player of the year and featured in the 2014/15 Premier League team of the year.
But in his 18 months with United, Sanchez has lost both form and confidence, and now the Premier League giants are reportedly desperate to offload him and his reported ?400,000 a week salary.
Yet Sanchez has shown signs of his old self at the Copa America, where he scored the winning shoot-out penalty against Colombia to send Chile into a semi-final meeting with neighbors Peru.
He also scored in each of Chile's opening two matches, victories over Japan and Ecuador, meaning he's scored more times in this month-long competition than he did in the entire Premier League campaign for United.
According to Rueda, it boils down to one thing that is missing from his life in rainy Manchester: "love."
"Despite not playing for their clubs, they come here with commitment and forge a strong group."
