Read the full terms and conditions for each offer below.

Celta Vigo v Osasuna

Celta Vigo picked up 27 of their 43 points at home last season and Celta fans will be expecting big things with Rafael Benitez taking charge at Balaidos. They can open up with a win over Osasuna.

Chelsea v Liverpool

Chelsea won only one of their 20 Premier League matches against top-half teams last season and it might take time for the Blues to show significant improvement. Liverpool can edge to an away win.

Rennes v Metz

Rennes were ruthless at Roazhon Park last season, winning 15 of their 19 Ligue 1 home games, and Bruno Genesio’s reinforced side can begin the new campaign with victory over Metz.

Getafe v Barcelona

Barcelona took their foot off the gas towards the end of last season but the Catalan giants were dominant La Liga winners and should have too much firepower for potential strugglers Getafe.
