The relaxed Manchester City boss caused a stir on Friday when he turned up to address reporters in the striking, multi-coloured garment.
It was a far cry from the understated grey we have been used to the Spaniard wearing in his press conferences.
And some took it as a sign of self-assuredness as City look to retain their crown as champions of England.
Guardiola’s side took back control of the title race as they returned to the top of the table after Wednesday’s 2-0 win at Everton.
However, Guardiola appeared at ease when he was questioned before City take on Chelsea on Sunday and was even accused of wearing the jumper to kick-start the mind-games ahead of what could be a crunch weekend.
Journalist Adam Hurrey said on Twitter: “Can a jumper constitute title-race Mind Games?”
Harry Reekie from ESPN added: “Unbelievable confidence from Guardiola to roll that sweater out.”
One fan noted: “You don’t wear a jumper like this unless you know the league is yours. Confidence 100.”
Others were not so complimentary of the City boss’s style, though.
One observer said: “Pep Guardiola looking like a Children’s TV presenter today in a very natty jumper at his media conference.”
Another critic added: “That jumper Guardiola is wearing is giving me a headache just looking at it. Shocking.”
Journalist Simon Bajkowski said: “When you’ve got a City press conference at 1.30pm and an audition for Joseph straight after.”
All that took away from what Guardiola was actually there to discuss. He was quizzed on his team selection for the Chelsea game and admitted Kevin De Bruyne might be left out of his starting line-up again.
De Bruyne did not start the Everton victory and Guardiola admitted he faces a battle to find a regular place in his strongest XI.
“Maybe yeah. it’s quite possible, everyone knows it’s possible or not possible,” he said.
“At the end we judge the players for who they are but they are there to perform. There are times when teammates are in better condition, in football what you have done in the past – you have to do in future.”
On De Bruyne’s omission for the Everton clash, he added: “We try to control the players, he played the last two.
“At Everton he got a few minutes, I want him to play as much as possible he went out for five minutes and he was incredible,” Guardiola added.
“I want him to sustain that for a long time. when you’re out a long time, I don’t want him playing game, game, game.
“At Goodison they play with a lot of set pieces, we are not a tall team so we wanted players for that. We put John there and he showed me his personality.
“He is playing so good with and without the ball, that was the reason. We play another game and some important players are not going to play. That’s what it is.”
