Chelsea have been alerted following speculation that Barcelona and Bayern Munich have joined the race for Roma star Miralem Pjanic, La Gazetta dello Sport reports.
The 26-year-old has a £31million buy-out clause inserted into his contract, with the Serie A giants ready to let him leave in order to comply with threats from the Financial Fair Play.
Chelsea have emerged as potential suitors as they look to reinforce their squad after missing out on a Champions League spot for next season.
However, they may need to step up their chase for the midfielder after Bayern and Barca are believed to be ready to lure him away.
Bayern have been very active heading into the upcoming transfer window, having already secured deals for both Renato Sanches and Mats Hummels.
Pjanic featured a total of 41 times in all competitions for his side this term, scoring 12 goals while managing to provide another 13 assists.
