The Ligue 1 champions have dismissed suggestions they could bid for the Argentine following reports they were prepared to smash the world transfer record for his services
During the summer les Parisiens were rumoured to be ready to match Messi’s reported €250 million (£210m) buy-out clause in response to the Catalan’s public pursuit of captain Thiago Silva.
Al-Khelaifi was quoted in AS saying: “I haven’t spoken to Messi because I’m not interested. You would have to ask the Barça [resident (If he is available), not me.”
Since Qatar Sport Investment bought the club in 2011, PSG have spent approximately €270 million (£225m) on their playing squad, with Edinson Cavani the club's latest marquee signing over the summer.
But with one eye on Fifa’s financial fair play regulations, Al-Khelaifi stressed that Messi was too expensive for the club to consider.
He added: “I won’t pay what they say he’s worth. I’m a realist and that amount is unrealistic. I’m not thinking about the possibility at all.”
The 26-year-old ended a four-game goalscoring drought with two goals in the Blaugrana's 3-1 win over AC Milan in the Champions League on Wednesday.
