N'Golo Kante is one of these who have been looked at, but with the Frenchman reported to be close to signing a new deal at Chelsea, attention has turned to Gundogan.Gundogan's deal at City is set to expire in June, which would leave him available to speak to clubs regarding a pre-contract deal ahead of next season. The Germany international was Pep Guardiola's first signing at the Etihad in 2016, which has seen the 32-year-old win the Premier League four times in his six seasons at the club.While City could offer Gundogan a new deal, younger talents such as Jude Bellingham and Declan Rice are reportedly available in the summer. The club may feel that it is best if Gundogan is allowed to leave as a free agent upon the expiration of his contract. However, Gundogan is the current captain at City, showcasing how highly rated he is at the club.With Barcelona's recent financial woes, Gundogan would represent a good value transfer. The midfielder has been a reliable performer over the years and with his pedigree could help mentor youngsters such as Pedri and Gavi.
