Toulouse 0-1 Paris St-Germain

Undefeated Paris St Germain have won 18 of their 21 league games this season

Zlatan Ibrahimovic scored a late winner as Paris St-Germain moved 23 points clear at the top of Ligue 1 with a 1-0 victory at Toulouse.

The Swede headed his 24th goal of the season after David Luiz flicked on a corner 17 minutes from time.

PSG maintained their bid to become the first team to complete an entire French top-flight season unbeaten.

Monaco can go second and trim the champions' lead to 21 points with victory at Lorient on Sunday.

Laurent Blanc's side were made to work hard for a ninth consecutive victory.

But once Ibrahimovic had broken the deadlock, they could have gone on to win by a bigger margin as Toulouse left gaps at the back in search of an equaliser.

The sides meet again in Paris on Tuesday in the French Cup.

PSG have lost just once in 31 competitive games this season, a 1-0 defeat by Real Madrid in the Champions League in November.

Toulouse drop to second-bottom after a six-game unbeaten run came to an end.
