Thomas Tuchel

The German is one of the most highly-rated coaches in Europe, regarded as a brilliant tactician, despite having won just one major trophy, the DFB-Pokal with Borussia Dortmund last season. Tuchel, 44, has been without a club since leaving Dortmund after two years last summer after falling out with club bosses. Paris St Germain are also said to be closing in on Tuchel.

Massimiliano Allegri

The unsung Italian manager has been in charge of Juventus since 2014 and has guided the Turin giants to three Serie A titles and two Champions League finals. The 50-year-old has never managed outside his home country and there is no suggestion Juve are looking to make a change in the dug-out, but Allegri could be tempted by a new challenge in the Premier League.
