The 39-year-old Portuguese coach, who won two Primeira Liga titles with Sporting Lisbon, has signed a deal until 2027 and will join the club on November 11.

Ten Hag was released after a disastrous start to the season, with former Red Devils striker Ruud van Nistelrooy named interim boss.

Sporting CP manager Ruben Amorim has expressed regret regarding his recent meeting with West Ham United, saying it was 'a mistake' and one that he will have to accept and live with.

Mourinho was 41 when he left Porto and took over at a Chelsea side poised to dominate English football following Roman Abramovich's takeover. Now Amorim, at 39, is the favourite to replace Jurgen Klopp at Liverpool.
