20 big names missing from the English top flight.
20) Isco (Real Madrid)
After a difficult first season breaking into the starting lineup at Real Madrid, Spanish starlet Isco has been linked with a number of Premier League clubs this summer, most notably Liverpool. Manchester City were also known to be interested this time last year while he was still at Malaga, where he established himself as one of the best youngsters in the world. The 22-year-old can certainly recover his best form and would be the calibre of player warmly welcomed to England.
