Omar RichardsOmar Richards is close signing for FC BayernThe Reading left back is a free agent this summer and it is being said that Hasan Salihamidzic has set his eyes on the former England U21 international. Widely regarded by many as the best left back in the Championship, the Englishman is close to signing a contract with the European Champions.❗️(2/2) Update Omar #Richards: Saliham. & Neppe put in a lot of effort. #FCBayern was the most exciting transfer option for him. OR was not only offered the backup role for Davies. The left-footer can also play in central def., doubly interesting as Alaba is set to leave. @SPORT1— Florian Plettenberg (@Plettigoal) February 15, 2021He is versatile and can slot into left midfield and left center back positions as and when required to. He will fill the hole left by David Alaba next season and will primarily be acting as backup to Alphonso Davies in the left back position. Meanwhile, Lucas Hernandez moves into central defense post-summer.
