Mourinho also lashed out at his men for taking the victory over arch-rivals in the derby in the head and called the team "masters of complication" while shedding light on the shock defeat to West Brom. "You can not say that Manchester City won the title because Manchester United lost a game".
City had won convincingly against Tottenham Hotspurs on Saturday, leaving their fate in the hands of United team waiting to engage the Baggies the next day.
West Brom's victor arrived in the 73rd minute when Chris Brunt's corner was nodded back into the danger area by Nemanja Matic, under pressure from Craig Dawson, and Rodriguez stooped to head beyond David de Gea.
The United manager also criticized his team members and asked them to take an advice from Lukaku and Matic on why they start nearly every game. Probably because I won eight championships, I was not on the moon with the victory against them.
You've won every Premier League game in March and April has got off to a good start, too.
21 - top-scorer Sergio Aguero's league goal tally this season, third in the division behind Liverpool's Mohamed Salah and Tottenham's Harry Kane.
The result has heaped further pressure on Mourinho, whose side have been criticised at times this season for lacklustre performances which have led to a weak title challenge. "Our City. Premier League Champions 17/18". Previous times, we almost threw it away and that was a feature of every season we won it. People may say they bought the title but plenty of teams have spent significant funds. Three more wins will be enough to set a new mark.
"In general open play we had a couple of chances", he said. "Everyone is disappointed. We didn't play well at all and it's a bad afternoon for us".
West Brom were 12 points adrift of safety, winless in the league since January prior to kickoff and under the watch of caretaker boss Darren Moore, but offered the hosts an early warning shot with a couple of chances.
