Chelsea ban was lifted on Friday following their appeal to CAS. This has given them new hope for the season, and a way to do business with other teams in the world. Immediately after the ban was lifted, Frank Lampard made it known that he will be signing some players in the January transfer window. This also means some players may be leaving the team as more players will be joining.
Marcos Alonso hasn't been featured much under the management of Frank Lampard because Frank seems to like the ability of Emerson over Alonso. However, some Italian teams are seeing the great potential in Marcos Alonso, and they are willing to do business with Chelsea by January. These teams are Juventus and Inter Milan.
If they are really willing to sign him, he may also push to continue his career in one of the teams. The 28 years old spent 3 years in Fiorentina before he joined Chelsea, and if Juventus or Inter sign him, it will simply be a move back to where he was. His move depends solely if they are serious to sign him because Chelsea may also like to do this Business.
