Newcastle return to the bright lights of the Champions League on Thursday, but don’t expect to see Alan Shearer at St. James’ Park.Due to a scheduling conflict, a gutted Shearer will instead be thousands of feet up in the sky when Eddie Howe’s side take on Spanish giants Barcelona.Shearer will be one of several icons headed to the Premier League fan fest in Kansas City this weekendGettyWhy will Shearer miss Newcastle’s Champions League opener?“Can you believe it,” Shearer said on The Rest Is Football podcast.“The fan fest that the Premier League do in the United States, this has been arranged for such a long time.“I am going to Kansas and my flight’s on Thursday. Can you believe that?“I’m going to miss the game. I can’t believe it. Nightmare for me, unfortunately.”Shearer’s presence will be sorely missed given he has been there for some of Newcastle’s finest hours in recent seasons.The Toon legend was on hand at Wembley to watch his former club end their 70-year trophy drought with a 2-1 win over Liverpool in the Carabao Cup final last March.Shearer was also present to witness the Magpies thump Paris Saint-Germain 4-1 in October 2023.How did Newcastle qualify for the Champions League?Thursday marks Newcastle’s first game in the Champions League after a season away having finished fifth in the Premier League last term.Toon fans were made to sweat on the final day due to a 1-0 loss to Everton, which left them vulnerable to drop out of the top five.However, Aston Villa’s 2-0 defeat away to Manchester United ensured Newcastle would finish in the qualifying spots for the Champions League.Newcastle's Champions League fixturesSeptember 18: Newcastle v BarcelonaOctober 1: Union Saint-Gilloise v NewcastleOctober 21: Newcastle v BenficaNovember 5: Newcastle v Athletic ClubNovember 25: Marseille v NewcastleDecember 10: Bayer Leverkusen v NewcastleJanuary 21: Newcastle v PSV EindhovenJanuary 28: Paris Saint-Germain v NewcastleHow did Newcastle perform when they were last in the Champions League?This season also marks the first time Howe’s side have competed in the new-look format of the Champions League, with the group stage replaced by the league phase.In the 2023/24 season, Newcastle were drawn in a group with PSG, AC Milan and Borussia Dortmund.Despite a draw and win against Milan and PSG respectively from their opening two fixtures, Newcastle lost three of their next four Champions League matches.It meant they ultimately finished dead-last in their group with five points, three behind third-placed Milan.Additionally, Howe’s side scored only two goals and conceded six outside of the 4-1 thrashing of PSG as they endured a brutal reality check of what it’s like competing among Europe’s elite.But the Magpies will no doubt be stronger for the experience and will get eight games instead of six to prove they belong at that level.GettyClub-record signing Woltemade got Newcastle’s league campaign up and running on Saturday[/caption]Newcastle find themselves 10th after their first win of the seasonNewcastle’s results this seasonIt has been a mixed start to the campaign for Newcastle having won just once in their opening four league fixtures.However, that victory came on Saturday as new signing Nick Woltemade scored on his debut to hand Newcastle a 1-0 win over Wolves.The towering German rose to power home a header off a Jacob Murphy cross on the right.However, Howe will be without two of his other summer signings for Thursday’s clash as Jacob Ramsey and Yoane Wissa remain sidelined with injuries.
