Manchester United have been advised by club legend Teddy Sheringham to pursue the signing of Alexander Isak, who is currently performing exceptionally well for Newcastle United. Isak has netted 15 goals in 22 matches this season. Sheringham expressed his belief that Manchester United holds significant appeal for any player and suggested that Isak might consider joining if an offer were made. Newcastle have placed a £150 million valuation on Isak, who they acquired for £63 million from Real Sociedad in 2022. However, Manchester United could face competition from other leading clubs such as Arsenal and Liverpool, who have also expressed interest in the Swedish forward. With United currently facing difficulties in the league and dealing with financial limitations, raising the necessary funds to meet Newcastle's valuation could be challenging. Additionally, United's recent investment in Rasmus Hojlund might make them reluctant to spend heavily on another striker.
