Rasmus Hojlund is already promising to be the next Manchester United flop that have managed to go on and succeed elsewhere.That is the verdict of European football expert Andy Brassell, who stated the Dane has ‘immediately clicked’ on loan at Napoli.Hojlund scored just 14 minutes into his Napoli debut against FiorentinaGettyHojlund needed just 14 minutes on his debut for Antonio Conte‘s men to open his Serie A account for the Italian champions on Saturday.The 22-year-old helped his new side maintain their 100 per cent record in the league during a 3-1 away win at Fiorentina.It was his first appearance for any club this season, having been left out of each of United’s first three Premier League fixtures.The striker, who was also excluded from the Red Devils’ Carabao Cup defeat to Grimsby last month, was made surplus to requirements after Benjamin Sesko’s arrival.talkSPORT reported in June that head coach Ruben Amorim preferred to keep Joshua Zirkzee and sell Hojlund this summer.Having initially expressed his intentions to stay and compete for his spot at United, the Denmark international was eventually forced to accept his future lay elsewhere.However, his decision to follow Scott McTominay to Napoli already looks to be an inspired one following his impressive debut.Hojlund’s strike doubled the visitors’ lead on the night after Kevin De Bruyne had opened the scoring from the penalty spot.It was his first goal since joining on a season-long loan from United, with an obligation to buy if Napoli qualify for the Champions League.If triggered, it would see him complete a permanent switch for £38million – just two years on from arriving at Old Trafford for £72m.European football expert Brassell said Hojlund has ‘immediately clicked’ at NapoliSpeaking on talkSPORT’s Trans Europe Express podcast, Brassell said: “Hojlund scored a fantastic goal to put them 2-0 up, and immediately he’s clicked.“He talked afterwards about what an incredible opportunity it was to go to Napoli. “It always felt like United were keener to get rid of him than he was to leave, and maybe he was just waiting for an opportunity that probably wasn’t going to come on his form over the last couple of years.“But really, the Romelu Lukaku injury has changed everything. “It meant they had to go back into the market for a striker when they thought they’d completed their transfer market. “And then he comes into the team, and a really supremely confident finish straight away.”Conte expects more positive performances to come from HojlundGettyHojlund is already on his way to matching the 14 league goals he scored for Man UnitedConte teases Man United after Hojlund’s Napoli debutThe ex-Chelsea and Tottenham manager fired a cheeky dig at the Red Devils after Hojlund hit the ground running on his return to Italy.“Hojlund is only 22 years old, we got him from Manchester United, seeing as it brought us luck doing that with McTominay,” Conte joked.Red Devils academy graduate McTominay was named Serie A’s Most Valuable Player after scoring 12 goals in 34 appearances en route to helping Napoli win the Scudetto in his first year in Italy.The Scottish star is part of a trend at United where players have regained their form after leaving the club.Lukaku, Marcus Rashford, Antony, Memphis Depay, Anthony Elanga, Dean Henderson, and Angel di Maria are just some recent examples.Man United took a £30m-plus hit to get Hojlund off the booksHojlund set to be latest transfer regretHojlund has now threatened to become the latest, just weeks after he was branded a ‘£70m trialist’ who is not Premier League quality.However, Brassell added to the Trans Europe Express podcast: “So you know when they say, ‘It’s not me, it’s you?'”“Well, it’s not him, it’s United, I think is clear here because he promises to just be the next in a long list of players who’ve looked way short of it at Manchester United but have managed to go on and succeed somewhere else. “I mean, what does that say for United? “Not just in the [Ruben] Amorim regime, but I think in successive regimes of United, if a player goes out there and just becomes the player that he always should have been, the player that United thought they were buying.“It’s a good deal for United until he has a good season and they pick him up for a fee that looks cheap.”
