Manchester United were humiliated in front of their fans at Old Trafford stadium on Saturday as they suffered a 2-1 defeat against their arch rivals, Mancester City.

Goals from City’s Kevin de Bruyne and Kelechi Iheanacho gave the Pep Guardiola’s side two goals lead before Zlatan Ibrahimovic reduced the deficit just before the break during a breathless first half.

The home defeat was coach Jose Mourinho’s first loss in four EPL matches since he joined Manchester United this season.

The Manchester derby defeat to United did not come as a surprise to many football pundits as the fixture had already been predicted to go either way following the array of stars on parade for both sides.

However, the shocking results in the EPL on Saturday were Liverpool 4-1 drubbing of reigning champions Leicester City at Anfield and Watford’s 4-2 away victory at West Ham.

Roberto Firmino and Sadio Mane put Jurgen Klopp’s side two goals ahead as they played at home for the first time this season and for the first time since expanding Anfield’s capacity by 8,500 to 54,000.

Jamie Vardy reduced the deficit to a single goal after Lucas’s mistake. But Adam Lallana’s fine strike restored Liverpool’s two-goal advantage and Firmino’s late effort wrapped up a worrying defeat for Leicester, who have won only one of their first four matches.

At the Olympic Arena, Michail Antonio’s two goals in 33 minutes seemed to have sealed victory for West Ham, but it all fell apart as Watford seized control through Odion Ighalo, Troy Deeney and Étienne  Capoue.

José Holebas completed the rout just past the hour mark to give new manager Walter Mazzari his first win.

Other three shocking results across Europe on Saturday were:

— Barcelona suffered a shock home defeat by newly promoted Alaves as manager Luis Enrique left Lionel Messi and Luis Suarez on the bench.

Brazilian forward Deyverson silenced the Nou Camp when he stabbed home Kiko Femenia’s cross from seven yards. Barcelona’s defender Jeremy Mathieu headed the equaliser from Neymar’s corner to give the Nou Camp side a lifeline but Ibai Gomez scored the winner – beating debutant keeper Jasper Cillessen from just inside the area.

— Monaco handed down a thumping 4-1 home defeat to Lille on Saturday with goals from Djibril Sidibe, Adama Traore, Fabinho and Kamil Glik ensured a comfortable victory for Leonardo Jardim’s men.

Julien Palmieri added a late consolation for Lille but it did nothing to salvage a disappointing night for Frederic Antonetti’s lads.

— Newly promoted Bundesliga club RB Leipzig on Saturday recorded a shocking 1-0 victory against former champions Dortmund.

Scotland’s Oliver Burke marked his RB Leipzig debut by setting up a late goal for Naby Keita to secure the victory.

Leipzig are fifth and Dortmund eighth in the early Bundesliga table, with most teams having played twice.
