Enrique won the La Liga title and the Copa del Rey before adding the Champions League title with last Saturday’s 3-1 victory over Juventus in Berlin.
“We’ve closed the deal for Luis Enrique to remain as Barcelona coach until 2017,” Bartomeu said at a press conference on Tuesday afternoon.
The 43-year-old coach had cast some doubts over whether or not he would remain with Barcelona following Saturday’s victory.
Enrique appeared to be on the verge of the sack following a poor run of results at the start of the year and a dressing-room spat with Lionel Messi. However, the club’s board have decided to reward him with an improved contract.
