The 30-year-old is the star of the Great Britain squad just a year on from taking the 5,000 and 10,000 metres titles at London 2012.
Farah is odds-on to match his Olympic successes this week at the Luzhniki, where his campaign gets under way on the opening day of the championships.
Today will be his first 10,000m race on the track since last year’s Olympic final and gives him a chance to make amends for two years ago.
Ethiopia’s Ibrahim Jeilan’s late burst denied him gold in Daegu, but UK Athletics performance director Black does not see any such challenges for Farah this time around.
“His expectation is higher than anyone else’s,” said the man acting as successor to Olympic athletics chief Charles van Commenee.
“He will, without doubt, expect to win.
“It will take an amazing performance for that not to happen so we will find out what happens.
“He is in great shape. He arrived last night, we checked him out physically.
“He is a confident guy and looking forward to it.
“Bring it on, as far as he is concerned. He just wants to get on and enjoy it.”
Farah finalised his preparations for the championships with high altitude training in St Moritz, Switzerland – a far cry from the life he has enjoyed since London 2012.
Becoming a household name brings with it extra responsibilities, but Black knows he does not have to worry about Farah’s mentality.
“He has an amazing ability to switch and, using his own words, he lives the dream,” he said. “He chills out wherever he is.
“He doesn’t let journeys bother him, circumstances bother him – he doesn’t let anything get in the way.
“He can use time in a way he finds interesting and exciting, but when it comes to the competition he stays relaxed up until the final few minutes.
“Then he takes a real concentrated approach, purposeful and because he has such huge confidence I think a number of people are beaten before he even steps on the start line.
“I think it is that ability to go from completely chilled, completely relaxed to absolutely targeted, focused and an absolute belief in his ability to perform.”
Former world 1,500m champion Steve Cram believes Farah, pictured, intimidates his rivals and Black, acting as head coach after Peter Eriksson’s departure earlier this year, agrees.
“Because he is so relaxed and so confident it probably does in a way that is different to some others,” he said.
“Some will try to intimidate others by making themselves bigger or appearing to be almost overtly confident.
“I think Mo in his almost casualness is probably doing a similar thing, saying ‘if you guys think I’m that bothered, let’s see what happens on the track’.”
Farah himself feels a different athlete to the one that rocked up in Daegu two years ago.
“I am definitely a different athlete in terms of what I’ve done, in terms of confidence,” he said.
“Daegu was the start and to come back in 2012 and win that and now 2013, I’ve been sort of mixing and matching a little bit. I started off with the half marathon and then coming through 5k, 10k.
“I am just that bit stronger, I’ve been injury free, that’s the most important thing. Your body allows you to do 100 plus miles week in, week out. You have done that base so I am just stronger.”
The only other medal decided today is the women’s marathon, where Britain’s Sonia Samuels and Susan Partridge will be hoping to impress.
As if the task facing Leeds University PhD student Partridge – the top ranked of the two Britons – was not tough enough against a field led by three Africans, who not only have best times of over 10 minutes faster they are also undoubtedly better acclimatised than a runner bred in Oban, Scotland, and now resident in Yorkshire.
Partidge said: “I’d rather not be setting out at the hottest part of the day but clearly our comfort wasn’t a priority when they set the timetable.”
Ethiopian record holder Tiki Gelana, who won Olympic gold in London this time last year, has run 2:18:58 during the qualification period, and Kenya’s Lucy Kabuu and Edna Kiplagat have also gone sub 2:20.
Yet Partridge, 33, is also in the form of her life, having carved over three minutes off her personal best when emerging as the fastest British runner in last April’s London Marathon.
Her goal is to better the 24th place achieved on her World Championship debut in Daegu in 2011.
