Jose Mourinho’s side, who wrapped up the league title last weekend with three games to spare, had previously announced plans to play Sydney FC at the ANZ Stadium on June 2.
“We are very pleased to finalise our post-season schedule and I look forward to visiting Bangkok again,” chairman Bruce Buck told the Chelsea website.
“Our visits to Asia are always memorable, and I know the team will be well received by our tremendous supporters in Thailand. I am sure Jose and the team will deliver a performance to entertain as we celebrate what has been such an excellent season.”
Chelsea, who also won the League Cup this season, are due to play in the International Champions Cup friendly tournament in North America in July as part of their preparations for the 2015-16 campaign. – Agence France-Presse
