Lionel Messi helped Paris Saint-Germain clinch a record 11th French league title, and broke another scoring record in the process.

Messi scored the opening goal as PSG drew 1-1 at Strasbourg to move four points clear of second-placed Lens with one game left.

Messi put PSG ahead from Kylian Mbappe's pass in the 59th minute. Former PSG striker Kevin Gameiro equalised for Strasbourg in the 79th.

It was Messi's 496th career league goal in Europe, breaking Cristiano Ronaldo's scoring record for Europe's top five leagues. It could also be his last, as the Argentina star is widely expected to leave PSG at the end of the season and has been linked with a possible move to Saudi Arabia or MLS.

Lens secured second place and automatic entry into next season's Champions League by beating Ajaccio 3-0 at home, with Belgium's Lois Openda reaching 20 league goals in his first season at the club.

Defending champions PSG overtook former French powerhouse Saint-Étienne, which won their 10th title in 1981 but were relegated to the second division last season.

PSG have won nine of their 11 titles since Qatari backers QSI took charge 12 years ago, with the first of those in 2013. PSG’s other titles were in 1986 and 1994.

"This is of course an historic moment for Paris Saint-Germain. This 11th French league title is the reward for all the hard work we have put in over the last 12 years," said PSG president Nasser al-Khelaifi. "To make Ligue 1 history and overtake Saint-Etienne is a real source of pride."

The title will be celebrated next Saturday at Parc des Princes when PSG host Clermont in what could be Messi's last game for PSG.
