Pasalic signed for Chelsea over the summer, before immediately leaving the club on loan to join La Liga bottom club Elche.
The 19-year-old has turned out 11 times for his loan team, but has failed to register a single goal or assist, despite playing as something of a creative midfielder in the Franjiverdes starting XI.
Having signed a four-year deal with the Blues last season, the youngster - likened to both Frank Lampard and Michael Ballack for his style of play - is expected to become a key part of Jose Mourinho’s side in a few years, although the loan deal away from Stamford Bridge makes sense at the current stage of his career.
However, the failings of his loan spell with Elche have given cause for the Blues management to rethink the destination, and reports are suggesting that a deal has been agreed with Turkish club Besiktas to send the once-capped Croatian international to the Super Lig for the second half of the ongoing campaign.
The Blues recently started a partnership agreement with Besiktas, and rumours have abounded in recent weeks that a number of Stamford Bridge’s highest-rated prospects could be completing short-term deals to the Turkish side - such as utilised with Eredivisie side Vitesse. Kurt Zouma is the highest profile player to be linked with a switch to the Black Eagles, although there is still no confirmation from the Blues whether their 20-year-old central defender has actually agreed a deal with the side.
Not only will a switch to Besiktas allow Pasalic to enjoy first-team football in a side who are used to winning - rather than being rooted at the bottom of La Liga - but the partnership agreement will allow the Blues management team to enjoy increased interaction with the training and tactical systems that the 19-year-old is introduced to during his loan stay.
