Tino Livramento (Southampton)
Chelsea allowed their talented fullback to leave Stamford Bridge in the summer of 2021 for just £5m, before he went on to excel during his first season at St Mary’s.
However, a serious knee injury set back Livramento’s development and he hasn’t played since the end of April last year.
It hasn’t stopped the 20-year-old from being linked with Arsenal and Manchester City, but Chelsea do have a £50m buyback clause. Due to sell-on fees, the cost of the deal could even be lowered to £38m.
