Chelsea are interested in signing Tottenham defender Danny Rose, report The Mirror.
Yet their search for another left-back only serves to underline poor choices made by Jose Mourinho over the past 12 months.
The signing of Filipe Luis from Atletico Madrid proved a disaster, with the Brazilian failing to settle in England, and re-signing for the Spanish side last week.
Chelsea made a loss on the deal, as reported by The Mail, and are now searching for a defender to provide competition for Cesar Azpilicueta.
This highlights what a poor decision it was to get rid of Ryan Bertrand last summer, in order to accommodate Luis.
Bertrand had an excellent season at Southampton, earning an international call-up for England, and was one of the Premier League's most consistent players.
He played 3,000 Premier League minutes last season to Rose's 2,300, and is flourishing from first team football.
If Rose is worth a speculated £16 million as report The Mirror, there is an argument that Bertrand, who they sold, is worth an equal amount.
Rose would be an expensive admission of failure for Tottenham, and one which is no guarantee to pay off.
