Chelsea will have to fight off the likes of Inter Milan and Bayer Leverkusen if they want to land Barcelona defender Martin Montoya.
According to The Sun, the Blues are keen on the Camp Nou youth product as they look to bolster their back line at Stamford Bridge.
Montoya come through the ranks at Barcelona's famed La Masia academy but his route into the first team has been blocked by the form of Dani Alves.
Chelsea have sufficient numbers at right-back, though Mourinho's arrival has seen Spain international Cesar Azpilicueta limited to one start all season, with Branislav Ivanovic preferred in that position.
Montoya was reportedly set for crunch talks over a new deal at Barcelona, but will only agree to new terms if he is given assurances over regular first team football.
Mourinho's former club Inter Milan and Bundesliga side Bayer Leverkusen are both credited with an interest, but Chelsea's financial power should make them favourites should it come to a bidding war.
However, with Ivanovic installed as undisputed first choice in Montoya's position, he may find moving from Barcelona over first team assurances to a similar situation an uninviting prospect.
