Andy Brassell believes Anthony Gordon cannot afford to rest on his laurels, even if Barcelona ‘really needed him’.Gordon joined from Newcastle before the World Cup and has quickly taken to life at Barcelona, registering five assists from his first six appearances.Gordon has essentially replaced Marcus Rashford as Barcelona’s left-wingerGettyBut it’s not just Gordon’s attacking contributions that have made him so vital to Barca’s early season success.Anthony Gordon has been what Barca needed“It’s just the work he gets through off the ball,” European football expert Brassell said on Monday’s Hawksbee and Jacobs.“He’s ideal for them. They’ve really needed him because they weren’t able to get Julian Alvarez, so they’ve been playing Raphinha as a centre-forward.“Who knew, he’s (Raphinha) absolutely brilliant at it.”Raphinha, who moved to Barcelona from Leeds in July 2022, has netted eight times in all competitions this season.Previously a left-winger, the Brazilian’s shift to centre-forward has proved transformative.However, talkSPORT understands Raphinha is not seen as a long-term solution up front, with Harry Kane and Erling Haaland viewed as alternative targets should Barcelona fail to land Alvarez.Which Barcelona teammate should Anthony Gordon be concerned about?That could spell trouble for Gordon, who could be nudged down the pecking order if Raphinha is moved back to the left-wing.But Raphinha isn’t the only teammate Gordon has to worry about being usurped by.“He’s got good competition to keep him honest,” Brassell said.Raphinha has now scored over 80 goals for Barca since he moved from LeedsGetty“Karim Adeyemi came on for him and scored the clinching goal near the end.”Like Gordon, Adeyemi moved to Barcelona in the summer.However, Adeyemi, who joined from Borussia Dortmund, has started just twice for the Catalan outfit this term.The 24-year-old started Barcelona’s LaLiga opener where he got on the scoresheet in a 5-0 rout of Elche.But since then, Adeyemi has been reduced to cameos ranging from 28 minutes to 10.Even if Adeyemi is reduced to being Gordon’s back-up on the left, at least for now, it still leaves Barcelona with a strong attacking option to call on when needed.Adeyemi’s goal against Levante was Barcelona’s 21st from five LaLiga fixturesGettyBrassell: Barcelona may be scoring for fun, but they won’t win Champions LeagueAnd Brassell believes that spells bad news for the rest of the competition, as he claimed Barcelona will ‘end up winning LaLiga by an absolute mile.’Brassell’s belief is backed up by Barcelona’s blistering goalscoring rate, with Hansi Flick’s side netting 26 goals in just six games across all competitions this term.Should Barcelona maintain that rate and play 57 games, which was how many they played last season, they are on track to score an absurd 247 goals.However, he’s not-so-certain about their Champions League aspirations and pointed to their defence that has shown a worrying tendency to be too casual as the potential reason why.“Defending like they are defending at the moment, they will not win the Champions League, I don’t think,” Brassell said.“They’re competitive, they can play anyone off the park, there’s no doubt about that. They can score goals galore.“Can they keep it out against top level opposition? That’s the question.”
