Chelsea midfielder Carney Chukwuemeka has agreed to join Borussia Dortmund on loan.
The 21-year-old was due to fly from Biggin Hill to Paderborn, Germany, on Sunday ahead of his medical on Monday.
The deal will include a buy option higher than his £40m release clause while Dortmund will also cover his salary and pay a loan fee.
Porto had hoped to beat the Bundesliga giants to Chukwuemeka, as Manchester City continue to push for their midfielder Nico Gonzalez.
Chelsea had wanted him to go to Strasbourg on loan initially to continue his development with Liam Rosenior.
However, the former Aston Villa midfielder wanted to play in a stronger league. Everton, West Ham and Juventus had also shown interest.

The 21-year-old has not made a single Premier League appearances for the Blues this season
Chelsea signed Chukwuemeka for £20m from Aston Villa in 2022. He has largely spent this season in the cold under Enzo Maresca at Chelsea, going completely unused in the Premier League.
Chukwuemeka has made five appearances in total this term with four coming as a substitute and all in cup competitions.
His only start was in the Conference League dead rubber with Astana in Kazakhstan.
