Carson, 20, started his career at Leeds and played just 2 league games before a £750,000 move to Liverpool in January 2005. Since then he's started 9 games for Liverpool (4 league, 2 cup and 3 Champions League - inc a quarter final tie against Juventus) before a loan spell at Sheff Weds to end the 2005 / 06 season.
Carson is a huge prospect but could still find himself third choice at Liverpool behind Reina and Dudek so could be loaned out again by Liverpool with City said to be very interested.
