Jose Mourinho has tried out a few various formations, setups and player combinations since the start of the season but it's obvious he still doesn't know what his best team is.
The Manchester United manager suffered his third Premier League defeat of the campaign at the hands of old side Chelsea at Stamford Bridge on Sunday.
It has ramped up the pressure on Mourinho to turn the team's fortunes around and he will need to stumble upon a winning combination sooner rather than later to stay in touch with the title challengers.

The term 'crisis' might be too premature at this stage but as with any bad patch of form, pundits are constantly wading in with possible solutions and it is no different this time around.
Former Red Devil Owen Hargreaves, who is now more commonly seen on BT Sport, believes one Man United player isn't being used enough by the Portuguese manager.

Henrikh Mkhitaryan was voted the Bundesliga Players' Player of the Season last term but has failed to get going at Old Trafford since his summer move from Borussia Dortmund.
Injury problems certainly haven't helped but even now the Armenian has returned to full fitness, he has struggled for opportunities of late.
And his continued absence from the starting XI has left Hargreaves perplexed.
"He needs to play, I can't believe that he's not getting a look-in. He would be a banker in my starting XI," Hargreaves told Squawka.
"He had a slow start at Dortmund too and he was the players' player of the year last season. He got 23 goals and 32 assists, which is staggering numbers.
"This wasn't in a terrible league against pub teams and I can't think of anybody who could put up those numbers besides Messi and Ronaldo. He's a top player and we haven't seen it yet at United."
Of course, Mkhitaryan wouldn't be the first big name to struggle to adapt to the Premier League.
Hargreaves fears a fragile mental state could have affected the ex-Dortmund's ace early season form and thinks a goal in his first few matches could have made all the difference.
He added: "The thing is, he's such a wonderful player but I think he's also quite a sensitive guy.
"It would have been perfect if he started off flying with goals and assists, but the slow start has probably hit his confidence."
Mkhitaryan hasn't featured since being substituted off at half-time during the defeat to Manchester City in September - the Red Devils' next opponents in the EFL Cup on Wednesday.
