Sevilla's former Chile boss Jorge Sampaoli is Sky Bet's market leader to be the Barcelona manager at the start of next season.
Current Barca boss Luis Enrique has confirmed he will not be at the helm next term, the 46-year-old making the statement after his side's 6-1 win over his first club Sporting Gijon on Wednesday night, and bookmakers make Sampaoli the early front-runner at 2/1.
By Thursday morning, Athletic Bilbao coach Ernesto Valverde had been backed in from 9/1 to 11/4 second favourite.
Everton manager and former Barcelona defender Ronald Koeman is another who has been linked with the top job at the Camp Nou but he has drifted from 6/1 to 8/1 in the early betting. Arsenal boss Arsene Wenger remains steady at 6/1.
Tottenham fans are also likely to be slightly worried by the news, with Mauricio Pochettino attracting praise across Europe for his work with Spurs. And, despite his Espanyol roots, he's 12/1 to take charge of Barcelona for the first game of the 2017/18 campaign.
Atletico Madrid manager Diego Simeone has drifted from 20/1 on Wednesday night to 28/1, while Frank de Boer, Oscar Garcia and Pep Guardiola - who only left Barca for Bayern Munich in 2012 - are all 20/1.
