Ander Herrera believes Paris Saint-Germain would struggle to sign Lionel Messi this summer due to Financial Fair Play regulations.
The Barcelona talisman has been linked with a move to the French champions since he handed in a shock transfer request last summer, and is available to leave the Nou Camp on a free at the end of the season should he choose not to renew his contract.
The 33-year-old has also been linked with Manchester City, with the two state-owned clubs the only real plausible candidates to afford his eye-watering wages.
