Borussia Dortmund boss Jurgen Klopp is reportedly emerging as Chelsea owner Roman Abramovich's first choice to take over at Stamford Bridge.
The 44-year-old is high on the list of contenders after winning the Bundesliga with Dortmund last season, according to the Daily Mail.
Klopp's current deal with the German club runs until 2016, but Abramovich could attempt to buy out his contract at the end of the season.
Real Madrid boss Jose Mourinho and Barcelona manager Pep Guardiola are also among those on the wanted list.
