The Turkish club are assessing two players from the same Serie A side, with defensive reinforcements a priority for the second half of the season.
According to reports in Italy, Solet has emerged as a serious option for the Istanbul club. The French-born defender, who represents Ivory Coast internationally, has attracted attention through his performances for Udinese and is understood to be among the players Italiano would like to bring to Turkey.
Besiktas are considering opening discussions with Udinese during the January transfer window. Solet has ambitions of testing himself at a higher level, and the possibility of joining a club with European ambitions could appeal to the centre-back.
His recent international recognition has also raised his profile. Solet received his first call-up to the Ivory Coast squad for the latest international fixtures, an important development in his career after previously representing France at youth level.
The 26-year-old is not the only Udinese player being monitored by Besiktas. Nigerian goalkeeper Maduka Okoye is also understood to be on the Turkish club's list of potential January targets.
Besiktas had already shown interest in Okoye during the summer transfer window, but a move did not materialise. The goalkeeper's difficult spell has reportedly encouraged the Istanbul side to reconsider an approach, with a change of club potentially offering him the opportunity to rebuild his confidence and regain momentum.
The two players would address different areas of the squad, although the wider objective is the same: to improve the quality and depth of Italiano's options. Solet would provide an additional option in central defence, while Okoye could offer competition in goal.
At this stage, the reported interest does not amount to an agreement or an advanced negotiation. Besiktas are assessing the possibility of approaching Udinese, and the Italian club's position on either player remains an important factor in determining whether discussions progress.
The January window is still some distance away, but the interest in both players suggests that Italiano's recruitment plans are already taking shape. A move for Solet would be an attempt to strengthen the defensive line, while a renewed pursuit of Okoye could provide an opportunity to bring in a goalkeeper who has previously attracted the club's attention.
For Udinese, the prospect of losing two members of their squad in the same window would require careful consideration. Whether Besiktas turn their interest into formal offers will become clearer as the transfer window approaches.
