It was clear to see Chelsea were far from their once-dominant selves when interim boss Guus Hiddink returned to Stamford Bridge for his second spell in charge.
Following the sacking Jose Mourinho, change was needed in west London - and change is indeed what Hiddink has brought since his arrival in December.
Various improvements have been made under the Dutchman's tutelage, of which midfielder John Obi Mikel believes communication has improved most.

The Nigerian told BBC's Match of the Day: "It's the way he communicates with the players and maybe that's what the players felt they didn't get from the previous manager.
"Sometimes players - not just because they're not playing - you need to communicate with them. You need to speak to them and don't just ignore them because players like to be communicated to.
"This is what [Hiddink] has brought into the football club. In some ways you barely know he is in there, he is that calm and relaxed."
Chelsea were 16th in the Premier League when Hiddink replaced Mourinho, one point above the relegation zone; now, the Blues sit 13th, 14 points adrift of the top four and with hope of a top-four spot lingering.
The 69-year-old took charge of a team lacking confidence, and following an unbeaten league run of nine games, it certainly seems like the Blues are rediscovering their best football.
And recent results will only add to the new-found spirit and belief at Stamford Bridge, following a 1-0 away victory over Arsenal and last weekend's 5-1 drubbing of MK Dons in the FA Cup.
Hiddink's side travel to Watford on Wednesday night, with the hope they can extend their streak and maintain their faint bid for a Champions League spot.
