Newcastle consider Borussia Dortmunds Felix Nmecha as potential Bruno Guimares replacementLquipe reports that Newcastle United have identified Borussia Dortmund midfielder Felix Nmecha as a potential replacement for Bruno Guimares. The Premier League club are preparing for the possible departure of their captain amid serious interest from Arsenal.The French sporting publication claims that Arsenal and Newcastle are approaching an agreement worth 90m before bonuses. Reports in England have been more cautious, with Newcastle said to have rejected an opening offer and continued to demand an improved package for the 28-year-old Brazilian international.Newcastle are nevertheless exploring possible successors should Guimares leave St James Park. Nmecha has reportedly emerged as a clear target for the central midfield position, although Lquipe provides no information on an official offer or direct negotiations with Dortmund.The Magpies are believed to be aware of Dortmunds conditions for considering a sale. Nmecha remains under contract through 2030 after signing an early two-year extension in March, leaving die Schwarzgelben in a strong negotiating position.Newcastle revive long-standing Nmecha interestNewcastle already considered signing Nmecha before his move from Wolfsburg to Dortmund in the summer of 2023. The Hamburg native ultimately chose BVB, who paid approximately 30m for the former Manchester City academy player.Felix, along with his older brother Lukas, were both partially raised in England and speak the language fluently.Nmecha arrived as part of Dortmunds attempt to reconstruct their midfield following Jude Bellinghams move to Real Madrid. His first campaign at the Westfalenstadion was repeatedly interrupted by injury, preventing him from establishing consistent form.The German international subsequently developed into one of Dortmunds most important midfielders. Niko Kovac has praised Nmechas physical strength, technical ability and vision, while identifying the six and eight positions as his strongest long-term roles.Nmechas capacity to win possession, carry the ball through pressure and immediately initiate counterattacks also became central to Dortmunds tactical approach. His performances led Inter and Manchester United to register interest last summer, when BVB were reportedly seeking approximately 60m.His standing has increased considerably since then. Nmecha re-established himself in the German national team and emerged as one of the few positive performers during the countrys disappointing World Cup campaign. His estimated market value has now risen to 50m, making him the second most valuable player in Kovacs squad behind Nico Schlotterbeck.Dortmund hold strong negotiating positionDortmund have publicly maintained that they do not intend to sell Nmecha this summer. Sporting director Nils-Ole Book ruled out a departure at the end of May and described the midfielder as one of the best players in his position in German football.The club adopted a similarly firm position when announcing his contract extension. Managing director Lars Ricken described Nmecha as a central component of Dortmunds strategic squad planning and emphasised his importance both at club and international level.The new agreement reportedly contains a release clause, but it cannot be activated during the present transfer window. Sport Bild reports that Nmecha may leave for 80m in the summer of 2027, with the figure dropping to 70m one year later.Newcastle would therefore have to negotiate directly with Dortmund and potentially offer more than the value of the future clause to prompt a change in position this summer. Recent reports have suggested that BVB would demand approximately 100m to sanction an immediate sale.Such a sum would represent a major profit on Dortmunds original investment and provide funds for extensive squad reinforcement. Losing Nmecha shortly before the start of the Bundesliga season would nevertheless leave Kovac without one of the players around whom his midfield has been constructed.Nils-Ole Book on Nmechas futureFelix will play for us next season as well; thats the clear plan, Book told Sport Bild in May.GGFN|Peter Weis
