It's Hot or Not time as Sportsmail's DANIEL MATTHEWS tells us what's been making him feel warm and what's left him feeling cold this week...
HOT
VIRGIL VAN DIJK
Nine months after Jordan Pickford chopped him in half, Van Dijk returned to Liverpool first-team action in a friendly against Hertha Berlin.
So did centre back partner Joe Gomez. What a boost for Jurgen Klopp.
LEWIS HAMILTON
Remember when Bernie Ecclestone questioned Hamilton's fighting spirit? Well, whatever you think of his driving, Hamilton's refusal to shirk important battles endures.
Now he is unafraid to prod governments. Ahead of the Hungarian Grand Prix, Hamilton branded the country's proposed 'anti-LGBT+' law unacceptable and cowardly. He never was one who stuck to sport. And we should all be grateful for it.
LUTALO MUHAMMAD
Team GB's pursuit of taekwondo gold was a tale of oh-so-nears. Few viewers had any idea what they were watching.
But we were all gripped, thanks in large part to Muhammad in the BBC studio. The double Olympic medallist was charming, authoritative and insightful.
NOT
RASSIE ERASMUS
Wealways hear about that fine line and where it sits between genius and barmy.
Quite where we place Rassie Erasmus after the past few days is anyone's guess.
World Rugby 'noted' the hour-long monologue in which the Springboks director of rugby railed against the refereeing in the first Lions Test. The whole thing was bonkers and rather unbecoming.
BRITISH ROWING
The time for recrimination was always going to come — Britain's worst Olympic regatta since 1976 could not pass without a period of introspection.
But no one wins when the mud-slinging begins before the oars are even dry. 'Smug' predecessors, coaches accused of 'destroying' athletes… not a good look.
The ROC
You cannot blame the Russian athletes: all 335 of them, decked out in those 'neutral' colours of red, white and blue.
They have been allowed to compete, some were always going to triumph.
But the sight of 'ROC' towards the top of the Tokyo medal table is not the greatest advert for these Games — or the fight against state-sponsored doping.
