Matthias Jaissle will field a Newcastle team on Sunday for the first time and there will be no sign of Anthony Gordon, Bruno Guimaraes, or Sandro Tonali.The Magpies host Liverpool at St James’ Park on Sunday afternoon in their top-flight opener following a turbulent summer that saw the departure of Eddie Howe.Newcastle are enduring a testing summerGettyThe north-east club has spent over £165million to overhaul the first team, which was sourced from the £236m generated from selling core players.Newcastle’s hierarchy has shifted their recruitment strategy toward acquiring elite young talent.They have invested in a reliable No1 goalkeeper in Lukas Hornicek from Braga, alongside backup option Ewen Jaouen from Reims.Jaissle’s tactical approach is heavily influenced by the Red Bull coaching model, with his teams built around aggressive high pressing and intense counter-pressing.His previous sides aimed to recover the ball high up the pitch and attack quickly before opponents could reorganise defensively.However, the 38-year-old manager will be unable to rely on Joelinton in midfield after he confirmed the Brazilian faces at least two weeks on the sidelines with an unspecified injury.Additionally, Anthony Elanga was stretchered off during a pre-season friendly, while Tino Livramento remains doubtful as he continues to recover from the injury that forced him out of the England World Cup squad.How will Newcastle line up against Liverpool?Howe was wedded on his 4-3-3 formation at St James’ Park but the new Magpies boss will likely set his team up in a 4-2-3-1 shape, as frequently seen throughout pre-season.Jaissle explained his tactical philosophy: “It is not about formations that much. It is more how you want to play, how you want to attack, how you want to defend.Matthias Jaissle is working tirelessly to bolster his squad ahead of the big kick off on Sunday after getting bea in pre-season to Liverpool’s neighbours – EvertonGetty“If you understand that and the players understand that, tactically you are much more flexible and the formation is not that important.“These days the players are more and more involved in tactical things. Every coach and every club works with principles, so every player has to know a lot of things, tactically, in each phase of the game. I think that’s a big change.”One position locked in for the Magpies is in goal, with Lukas Hornick, signed from Braga for £25.7million on a five-year contract.The 24-year-old represents a key component of Newcastle’s summer rebuild after the side managed just eight Premier League clean sheets last season, conceding 55 goals.Nick Pope made a handful of significant errors leading to goals while Aaron Ramsdale never fully convinced during his loan spell and has since returned to Southampton.However, the rest of the team remains fluid following a frantic transfer window on Tyneside.Kieran Trippier completed a move to Wolves to help them in their fight for promotionGettyFollowing Kieran Trippier‘s exit at the the end of last term, the club addressed the right-back slot by signing Amar Dedic.The Bosnia and Herzegovina international moved from Benfica and is a forward-thinking, attack-minded full-back who registered four assists in Liga Portugal last season.Joining him in the back four are three familiar faces, with Malick Thiaw partnering Dan Burn in central defence.Thiaw proved reliable last campaign despite occasional individual errors and has worn the captain’s armband throughout pre-season.Meanwhile, despite Lewis Hall being just 21 years old, the technically gifted defender will be heavily relied upon by both supporters and his new boss this season – provided he is not sold before the deadline.The Magpies need to focus on replacing Guimaraes and Tonali in midfield, and were able to secure the signature of two risings talents in Aladji Bamba and Sean Steur from Monaco and Ajax, respectively.The duo marks a shift in transfer strategy for the club – taking calculated risks this summer before the talents potentially become out of reach.However, due to their relative inexperience in English football, Jaissle will likely opt for a reliable midfield pairing of Lewis Miley and Jacob Ramsey.Jeff Stelling has backed Miley for another strong season at Newcastle on talkSPORTGettyMiley was declared fit following his appearance in the friendly against Bayer Leverkusen, marking his return from a broken leg sustained in May.It was an emotional outing for the family, with the 20-year-old featuring alongside his younger brother Mason Miley.Ramsey played in a deeper role on several occasions under Howe last term, demonstrating his ability to carry the ball forward, though he will be expected to increase his goal-and-assist output.In attack, Jacob Murphy remains the strongest option on the right flank and has the ability to create chances in the squad. He registered three goals and two assists last season in the Premier League.On the left-wing, a fresh face for Newcastle fans is prepared to start and could be the player to define this new Magpie squad.Former Hoffenheim winger Bazoumana Toure impressed in the Bundesliga last term, ranking among the top ten fastest players in Germany while netting five goals and contributing nine assists.Operating behind the frontman is Yoane Wissa, who had an underwhelming campaign after signing for £55million on deadline day from Brentford.The forward suffered a knee injury on international duty with DR Congo and did not feature until December, looking short of match sharpness and managing just one goal and one assist in 19 league appearances.He will be supported by Will Osula, who proved his worth with a strong goalscoring run at the end of the 2025/26 campaign, netting seven times.One notable omission from the starting lineup is Nick Woltemade.Woltemade was dropped to the bench for a period last season amid his ongoing strugglesAlamyDespite arriving off the back of a 17-goal season in Germany, the 24-year-old struggled after being shifted into midfield roles.However, Jaissle might be the manager to change that, with the boss commenting on the players previous form.He said: “I saw that he had a difficult period. From the first day, we talked a lot. He should leave the past behind because it’s something we cannot change.”This could be how Newcastle start against Brentford next week
