Inter Milan are ready to let Fredy Guarin and Ricky Alvarez leave this summer with Chelsea and Manchester United keeping tabs. According to a report in Tuttosport, the relationship between Guarin and coach Walter Mazzarri is at an all-time low and the Colombian will be allowed to leave the club at the end of the season. Chelsea were close to a move for the 27-year-old back in January and could be tempted to go back in this summer if he can be bought relatively cheaply. Inter have apparently sent probes to clubs in the Premier League to generate some interest in the player as they look to rebuild this summer. Former player Javier Zanetti is set to take over as sporting director in the summer and will look to help Mazzarri focus his squad. Inter have also made attacking midfielder Alvarez available and United are keen on the player. The Argentine playmaker was holding out for a contract extension at Inter, but that has so far failed to materialise and he looks set to leave the San Siro. Alvarez is attracting plenty of interest around Europe with Borussia Dortmund and Monaco also keen.
