Watford's lineup against Manchester City looked like a surrender

Despite being on track for a quadruple - with a lead in the Premier League, the Carabao Cup triumph, an FA Cup quarter-finals appearance and UEFA Champions League round-of-16 advantage, issues of the pitch cast a shadow on their targets.

Sane was the one of the difference makers for Pep Guardiola's men in the first-leg at Germany with his 85th minute equaliser before Raheem Sterling struck in injury time to a seal a 3-2 win for City.

Within a minute of the restart, however, Sterling put City ahead with a controversial goal that was initially ruled out for offside before referee Paul Tierney changed his mind after lengthy consultation with his assistant.

Following prolonged discussions between the match officials, the goal was awarded despite Sterling being in an offside position when Aguero touched the ball into his path, because Janmaat played it against the England winger's shin for the ricochet into the net.

"The Premier League has previously contacted Manchester City to request information regarding recent allegations and is in ongoing dialogue with the club", a statement read.

There seems, however, no hope for Fulham under caretaker manager Scott Parker, after their defeat at Leicester, whose own new boss Brendan Rodgers was grateful for Vardy's late double.

"Of course, that's why I keep working", he said when asked about a possible future reunion with Guardiola at Manchester City. Other clubs didn't accept that.

"Next season we won't be having this conversation and we will be clear". The third was more impressive as Sterling collected a pass from Silva and went past two defenders before slotting the ball home.

"Guardiola was a very special coach for me, the first when I was at Barcelona. In my opinion, it is clear".

Should Sterling's opening goal have been chalked off? "After that, it is true the defender touches the ball, but he touches it because Sterling is close to him and is going to press him".

"He didn't help us a lot defensively in the first half and he gave the ball away".

The introduction of Troy Deeney and Gerard Delofeu immediately paid dividents for the visitors as the pair combined within thirty seconds of coming on for Delofeu to pull one back in the 66th minute. "Here there are many people working to make last season's level and if they can do that it will be down to hard work and not luck".

Nicolas Otamendi also headed wide of the far post as Watford struggled to contain a team desperate to improve their goal difference, but City were left to settle for three goals and three points as they took another step forward to retaining their league crown.
