Championship Derby County have agreed a deal to sign striker Chris Martin on a free transfer from Norwich City. The 24-year-old, who scored twice in 13 games while on loan at Pride Park this season, has agreed a two-year deal with an option for a third.

"It was great to have a look at him at close quarters this season ," boss Nigel Clough told BBC Radio Derby.

"We have admired him from afar and to get a player of his quality on a free transfer is a good deal."
