Nigeria international Kenneth Omeruo has become the longest-serving player at Chelsea following the sale of Czech Republic centre-back Tomas Kalas to Bristol City on Monday.
Kalas arrived at Stamford Bridge from Sigma Olomouc in July 2010 and departs The Blues after only four first-team appearances in nine years.
The title of the longest-serving player at Chelsea now belongs to Omeruo who joined from Nigerian side Sunshine Stars in January 2012.
The Super Eagles star has remained loyal to Chelsea despite the fact he has yet to make his official debut for the club after seven years and six months.
The 25-year-old, who is contracted to Chelsea for another one and a half years, has been linked with a permanent departure from the club in the summer transfer window.
