NYON: The tenure of Carlo Ancelotti as coach at Bayern Munich appeared ever more fragile after their 3-0 defeat by Paris Saint-Germain in the Champions League.

Bayern bosses such as Uli Hoeness and Karl-Heinz Rummenigge have been openly critical of the French club’s money-no-object spending campaign but their own ‘project’ was left looking decidedly second best.

The Group B saw PSG grab a second-minute lead through Dani Alves. Edinson Cavani then increased the advantage before half-time  with his 10th goal in as many appearances this season.

Fit-again Neymar added a third just after the hour-mark and appeared to put his recent spat with Cavani behind him to help lead Bayern a merry dance, while Kylian Mbappe was in breathtaking form as all three lived up to their star billing.

Also in Group B Celtic got their campaign up and running with an outstanding 3-0 win over Anderlecht in Brussels.

Striker Leigh Griffiths lit up a dull first half at the Constant Vanden Stock Stadium with a poacher’s goal in the 38th minute and five minutes after the break Patrick Roberts’ drive took a deflection in off substitute Kara Mbodji.

Anderlecht’s interim boss Nicolas Frutos stood on the sidelines frustrated as Brendan Rodgers’ side withstood everything the Belgian champions could throw at them before Scott Sinclair scored a breakaway third in added time.

Romelu Lukaku continued his remarkable scoring run with two goals as Manchester United swept aside CSKA Moscow 4-1 in Russia, on what was a fine night for British sides in the Champions League.

Lukaku he took his tally to 10 goals in nine appearances – the great Sir Bobby Charlton managed ‘only’ nine in his first nine.

The Belgian scored in his eighth successive European game with a double in the first half either side of an Anthony Martial penalty with Henrikh Mkhitaryan adding a fourth just after the interval.

In adding to his tally since swapping blue for red, Lukaku became the first United player to find the net in his opening two Champions League matches as the Red Devils established an early three-point lead at the top of Group A.

Substitute Konstantin Kuchaev’s 90th-minute goal was little consolation.

In Spain, Alvaro Morata and Michy Batshuayi proved there is life after Diego Costa as Chelsea fought back to win 2-1 at Atletico.

Costa, whose return to Atletico was completed on Tuesday, watched on as Chelsea responded from David Luiz’s needless concession of a penalty scored by Antoine Griezmann.

Former Real Madrid striker Morata headed in Eden Hazard’s cross for his seventh goal in eight games for Chelsea, before Batshuayi struck with the final kick of the game.

The dramatic finish gave the Blues two wins from two Champions League Group C games.

In other ties Benfica crashed 5-0 to Basel but Juventus won 2-0 against OlympiacosBarcelona edged Sporting 1-0 in Lisbon and Roma won 2-1 at K Qarabag.
