Manchester United paid more than $28 million for young Spanish goalie David de Gea, only for him to land on the bench after a series of erratic performances. Now comes word that the 21-year-old keeper may need laser surgery at the end of the season because he is far-sighted.

United was aware of De Gea's vision issues when it signed him from Atletico Madrid, which had recommended treatment for his vision problems but whose medical staff suggested he hold off on laser treatment until his prescription stabilized.

De Gea wore glasses for most of his life and now wears contacts. There is no evidence his erratic play is due to his vision, but those who wear contact lenses often find their eyesight is strained under artificial light.

De Gea has been very good at times, but mistakes have cost United as many as six to nine goals since he arrived last summer.
