The Bosnia international went to Boro in January of last season and proved to be an immediate hit with the fans and his strong performances on the left of midfield saw Boro come agonizingly close to making it back into the Premier League.
The 25-year-old midfielder joined Everton back in 2013, but has failed to maintain a regular role in the starting lineup. Last season at Boro he featured 17 times under Tony Pulis and showed that he had some flair and creativity to add to his bone-crunching style.
Besic got a few minutes during Everton’s preseason, but despite playing decently didn’t appear to have made an impression on Marco Silva. The midfield area has been cluttered but with Joe Williams leaving on loan earlier and now Besic gone too, there appears to be a clear hierarchy with the injured Beni Baningime backing up the also injured Morgan Schneiderlin.
