Napoli

The result in Naples could prove to be of great importance for Rosenior whose appointment in place of Enzo Maresca was hardly greeted with open arms.

Rosenior’s lack of elite experience – having moved from sister club Strasbourg after stints with Derby County and Hull City in the Championship – saw him labelled by some as a ‘yes man’.

He also experienced the wrath of the fans who voiced anti-ownership chants questioning the ambition of the BlueCo.

Rosenior has been adamant from the start that his reply must be through results.

And he has put together an impressive set of results in his first weeks with five wins in six matches and the latest over a former Chelsea favourite should win him the confidence of more supporters.

“These players lost a manager that they really respected for reasons that are beyond my control or knowledge,” Rosenior told TNT Sports.

“So when you go through that as a young group, to accept a new manager the way they have done and for them to work as hard as they have done is a credit to them.

“It’s not about me or my ego or trying to prove anything. I’m trying to do the very best I can with my group, with my staff and hopefully we can have more and more really good nights like this.”

Rosenior’s introduction of Cole Palmer at half-time provided assisted both of Joao Pedro’s goals while Trevoh Chalobah added defensive solidity after coming on later in the half as the Blues restricted Napoli to a single shot on target after the break.

The Chelsea manager added: “I’m learning all the time about my team, about what we’re capable of.

“I really wanted to be front-footed today. I wanted to go out and win the game.”

His impetus was rewarded with a win that helps Chelsea avoid adding a two-legged play-off to their already busy schedule.

“It’s massive – that is huge for us to be able to be able to work with the players on the training round,” Rosenior said.

Bigger challenges await Rosenior and his young squad as they enter the business end of the competition but the London-born coach is optimistic.

“You have to enjoy this job,” he said.

“We’re the luckiest people in the world to do this job. You have to enjoy these moments, but we want more.

“You’re in the Champions League, so at the end of the day you have to play against the best and beat the best.”

A Chelsea supporter has described his “shock” after being stabbed and taken to hospital before Wednesday’s Champions League match against Napoli in Italy.

Marcus, 22, who did not want to give his surname, said he and a group of Chelsea fans were targeted in the centre of Naples by a group of Napoli ‘ultras’ – a term used for hardcore supporter groups in European football.

“We turned a corner – it wasn’t technically an alleyway, but it felt like one because there were no lights,” he said.

“There were about 20 or 30 people, all in black, walking towards us as soon as we made eye contact. Some people knew what was happening and ran straight away.”

Marcus, who was with “seven or eight” friends, added: “It was definitely a shock. Everyone was shaken up when we eventually found the police.

“I was in shorts and they were covered in blood, with blood going all down my leg. We think it was a screwdriver – it could’ve been a Stanley blade. It was either that or a screwdriver.

“I didn’t really feel it until I started running away. My left cheek felt heavy, almost, and as soon as I touched it my hand was covered in blood.”

Chelsea have urged fans travelling to Naples for Wednesday’s Champions League game to “exercise extreme caution” after two supporters needed hospital treatment.

The Italian city has a long history of cases of away supporters being targeted by Napoli ultras.

“The club is aware of an incident that took place on Tuesday evening in Naples,” a Chelsea statement said.

“Two fans are being treated in hospital, having sustained non-life-threatening injuries. The club would like to remind all supporters to exercise extreme caution whilst in the city and take note of the advice shared ahead of this fixture.”

Fans on social media claimed Chelsea supporters had been stabbed, but there has been no official confirmation of how the injuries were caused.

Around 2,500 Chelsea supporters have tickets for the game, with fans urged to meet at designated areas so they can travel to the ground by shuttle bus under police escort.

In travel advice that was issued to fans earlier this month, Chelsea said: “During Uefa competition matches, attacks on away fans have sometimes occurred in Naples.”

Supporters have been urged not to walk around the city and to avoid wearing club colours or emblems that identify them as Chelsea fans.

Liam Rosenior’s side need a win against Napoli at the Stadio Diego Armando Maradona to go directly into the last-16 stage of the Champions League.

Their hosts – Serie A champions last season – are seeking a win to stay in the competition.
