Chelsea have announced The Yokohama Rubber Company Ltd as their shirt sponsor from next season in a five-year deal which is the Premier League leaders' largest commercial deal to date.
Chelsea, who agreed a 10-year kit deal with adidas worth in the region of £300million in June 2013, said the size of the deal with tyre manufacturer Yokohama Rubber was commercially sensitive.
But it has been reported the five-year contract is worth £40million per season, second only in the Premier League to Manchester United's deal with US car manufacturer Chevrolet, which is worth £47m per season.
Yokohama Rubber replaces Korean electronic giants Samsung, which has sponsored Chelsea since 2005 in a deal which was re-signed in 2013 and worth a reported £18m. Chelsea hope the shirt deal will help the club, owned by Russian billionaire Roman Abramovich, in their bid to be self-sufficient.
