The 25 year old has had an awful time with the London club since completing his move there last year, making just 7 Premier League starts for the Champions League Runners Ups. However it was a successful move business-wise for Chelsea as they stand to make £5.5 million for the former Reading star, who they got on a free transfer.
Sidwell's move could be seen by some as a possible replacement for Gareth Barry whose £10 million exit to Liverpool is looking ever likelier. A good signing all the same as Martin O'Neill is looking to push into the top 6 next season.
