After back-to-back Premier League defeats to Manchester City and Watford, Mourinho and his men were under pressure to get back to winning ways.
Speaking about Mourinho, Smalling claimed the Portuguese boss told his players there were over 70,000 fans in the stadium that wanted to be in their shoes.
“The boss really wanted to get the enjoyment factor across,” he said.
“He stressed how there is 70-odd thousand people in the stands who want to be in our shoes and in his shoes.
“It’s a case of realising how lucky we are and how we should go out there and enjoy it. You can see that everyone did enjoy it and the message clearly did get across.”
Mourinho’s message seemed to work as supporters witnessed one of the club’s most convincing victories since Sir Alex Ferguson‘s retirement.
The win released the pressure on Mourinho and his side, with the decision to bench Wayne Rooney going down well with fans.
