Jamie Vardy and Harry Maguire are among the Leicester City players to pay tribute to Vichai Srivaddhanaprabha following confirmation the club's chairman was killed in Saturday's helicopter crash outside the King Power Stadium.
Srivaddhanaprabha was one of five people to perish in the incident, from which there were no survivors.
The Thai businessman, who oversaw Leicester's remarkable Premier League-winning campaign in 2015-16, had watched his side's 1-1 draw with West Ham before leaving the ground in a private helicopter.
The aircraft came down shortly after take-off, crashing outside the ground. Srivaddhanaprabha was named among the dead on Sunday.
Leicester's players took to social media shortly after the announcement to voice their shock and grief at the death of a man they called 'The Boss'.
"Struggling to find the right words... but to me you are a legend, an incredible man who had the biggest heart, the soul of Leicester City Football Club.
"Thank you for everything you did for me, my family and our club. I will truly miss you... may you rest in peace... #theboss"
"Never have I ever come across a man like you. So hard working, so dedicated, so passionate, so kind and generous in the extreme.
