Chelsea face a battle to land Porto fullback Alvaro Pereira.
The Daily Mail says Chelsea are facing a battle with big-spending Paris Saint-Germain over Pereira.
Manager Andre Villas-Boas is keen to bring in a replacement for Yuri Zhirkov, who joined Anzhi Makhachkala last week for £13million and wants Uruguay international Pereira.
The 25-year-old was a regular under Villas-Boas at Porto, where he is a firm favourite, but that is reflected in the asking price with the player having a £25million buy-out clause.
Liverpool enquired about Pereira after his impressive displays at the Copa America, but were put off by the £15million asking price.
Chelsea would be willing to do business at that figure but PSG's interest allows Porto to auction the player to the highest bidder.
