Graeme Swann's retirement surprises Australia coach

Darren Lehmann says Graeme Swann's decision to retire from cricket with immediate effect is "a bit of a surprise".

The Australia coach says he believes Swann will go down as "one of the England greats" and wishes the off-spinner "all the best in retirement".

Swann took 255 wickets in 60 Tests - the sixth highest tally for England.
