This shifts the conversation to Chelsea's transfer policy in both windows. "One error, one goal".
But from an attacking perspective, it felt sorely lacking.
Conte has been linked with a return to the position he held before taking over at Chelsea, that of Italy head coach.
The floodgates opened after the break, though, as Kingsley Coman doubled the lead and Mueller grabbed his second midway through the second half.

This is the problem Conte must address ahead of a sure-to-be gruelling second leg at the Camp Nou on March 14. Also for him, when you are a player during a career you can make a lot of mistakes. We should have scored more.
"They don't miss. It's a magical duo". It can happen to lose two games.
The reasons Chelsea were without the ball for so long on Tuesday are twofold.
The Nigerian team was founded less than two years ago by US-born Adigun, who represented Nigeria in 100m hurdles at the 2012 London Games. Against Bournemouth we created chances to score but Watford was a really bad game. An impressive display at the Etihad would do the Belgian no harm at all. It's not a 50-50 ball when he's involved.
Antonio Conte's decision to rest both his strikers could also reflect his broader priorities for the season.
"I think our three strikers played very well, a fantastic game", the Italian responded.
Meanwhile, ESPN FC pundit Steve Nicol talked about Real Madrid's interest in signing Hazard recently, and he said Chelsea probably would not let him leave this offseason. It is more winnable and is a six-point game in the battle for the top four.
Michael Keane remains in contention despite struggling since moving to Everton last summer and Burnley's James Tarkowski and Ben Mee have been scouted regularly by Southgate this season, as has Lewis Dunk, of Brighton & Hove Albion. Pro Soccer Talk asked the Blues boss his thoughts about Hazard's performance as a false number nine. Sometimes, the volatility works in Chelsea's favour. He will be two-on-one against brilliant centre-backs, and he will tire pretty quickly and start making mistakes.
"But if I had to choose, I prefer to play like I did in the last 10 minutes, which was out wide".
But over the past few months the former Aston Villa and Bolton star has suffered an alarming drop in form. It has that (tantalizing?) ability of transforming an otherwise normal or dull week into a festival, or a nightmare, depending on which team passes to the next stage and which side the viewer is on. "We have to win, we have to score".
'I have a lot of trust in Christensen. "The Champions League is another competition".
