Both clubs finished below United last season in the Premier League yet Mourinho claims they are projected as "serial winners" despite failing to land a trophy since 2012 and 2008 respectively.
Courtois' replacement at Stamford Bridge is Kepa Arrizabalaga, who became the most expensive goalkeeper in history when Chelsea paid his €80m release clause at Athletic Bilbao, but reports United are ready to make Leicester City's Harry Maguire the world's costliest defender now seem unlikely to come to fruition. It is time for me to stop thinking about the market.
Bayern Munich defender, Jerome Boateng, decided against joining Manchester United because he does not think they can win the Champions League this season, according to Sky sources in Germany.
After securing the signatures of Brazilian global midfielder Fred and Portuguese teenage full-back Diogo Dalot early in the window, strengthening his centre-back options has been Mourinho's priority.
Speaking this morning, Mourinho said: "The market closes today". We go with everything we have in that first match.
"Is hard for me to understand, to feel, to believe we finish second".
Sergio Romero, Antonio Valencia, Diego Dalot, Marcos Rojo and Nemanja Matic were all unavailable for Manchester United in their most recent match due to injury - all of which are expected to remain out of action. "I keep saying that I won eight championships and three Premier Leagues but I keep feeling that second last season was one of my biggest achievements in the game". I am happy with all the players at the moment'. The tactics to be changed in Championship Manager you can just press a button.
"The list that I gave you before of the injured players is an important list and today after training I will speak with that group of players - because everybody is different physically and mentally - and see how they feel they are".
