Pep Guardiola does not want Danny Rose to quit football because of the racism he has suffered and Manchester City’s manager believes it is better to fight the issue from within the sport.

This week the Tottenham Hotspur left-back said he could not “wait to see the back” of the game because of the racism afflicting it yet Guardiola said: “Danny Rose has not to do that [retire]. Next Tuesday [when City meet Spurs in the Champions League], if I see him, I will tell him the best way to fight, to combat this kind of terrible situation, is fighting, being there every day. He’s an extraordinary player.”

Rose was the target of racist abuse during England’s Euro 2020 qualifier against Montenegro in Podgorica last month and has previously suffered it while on international duty.

The Everton manager, Marco Silva, echoed Guardiola’s thoughts, saying: “It is the worst thing I can hear in football [that Rose wants to quit]. It is really sad to hear. I can imagine how much it must hurt him to say it. To see a player feeling like this is sad for all of us in the game. I just hope the situation [with racism] can stop as soon as possible.”

The Professional Footballers’ Association said the way Rose feels is a “shocking indictment” of how racism is being handled. In a statement, the organisation said: “We have spoken to Danny directly, both after the Montenegro game and again today [on Friday], to ensure he is aware that we are on his side and here to support him as a union and as fellow professionals. To see a senior England international so disheartened with his profession is a shocking indictment of the current experience of many players worldwide.”

Kick It Out’s head of development, Troy Townsend, added that Rose’s comments are likely to be the starting point for players to up the ante in the fight against racism.

Townsend said that, as long as players feel they are being let down, they will get stronger in taking the matter into their own hands. “The authorities, with all their resources and power, are failing them time and time again,” he said. “So players have little choice but to take matters into their own hands. This isn’t the first time Danny Rose has opened up about racial abuse he’s received.

“Danny has said he can’t wait to see the back of football, citing his disillusionment with ‘politics in the game’. Mark my words – there will be more and more players speaking out and taking increasingly bolder steps in protest. And the sport’s image will suffer more. It’s a sorry state of affairs when a man is desperate to turn his back on his livelihood because his industry has failed to protect him – and so many others like him.”

In Italy this week, Juventus’s Moise Kean was racially abused by Cagliari fans with his own teammate Leonardo Bonucci initially suggesting the young forward “could have done it differently” and that “the blame [was] 50-50”. Bonucci later backtracked and issued a statement on Instagram saying: “After 24 hours I want to clarify my feelings. I was interviewed right at the end of the game, and my words have been clearly misunderstood, probably because I was too hasty in the way I expressed my thoughts.”

On Friday the Chelsea manager, Maurizio Sarri, spoke about the incident at Cagliari and also his own player, Callum Hudson-Odoi, who has suffered racist abuse recently. Asked what conversations Sarri had had with Hudson-Odoi on the subject, the Italian said: “He is very strong. He has a great character, a very strong boy. I don’t know …”

Sarri expressed surprise that Kean had suffered the abuse at Cagliari despite previous high-profile incidents at the club’s stadium, such as Pescara’s Sulley Muntari in 2017 and Blaise Matuidi of Juventus the following year.

“I was surprised that this happened in Cagliari because, usually, in Cagliari the atmosphere in the stadium is good,” Sarri said. “Bonucci made a mistake but I’m sure he probably wanted to say something different. I’m sure Leonardo is not a racist. He made a mistake, of course. We can only be an example for people but it’s very difficult to solve the problem.”

Kean’s manager at Juve, Massimiliano Allegri, said on Friday that Bonucci had “expressed himself badly”. Allegri, who was himself criticised for saying Kean should not have celebrated scoring against Cagliari in the manner he did, tried to set the record straight at the club’s press conference.

“Racism must always be fought against and is never justifiable,” he said. “With his mind still on the game, post-match, Bonucci expressed himself badly but realised this and apologised. These two things are distinct.”
