Paris: Paris St-Germain’s meeting with Bordeaux on Saturday is their last chance to do some fine-tuning before next week’s showdown with Manchester United, but the Ligue 1 leaders have some major issues to contend with before heading to Old Trafford.

PSG were the strong favourites when the draw for the Champions League last 16 was made, yet much has changed in the eight weeks since.

United have been revitalised on a run of nine wins and a draw in 10 games since Jose Mourinho was sacked and Ole Gunnar Solskjaer appointed as his replacement. They are likely to be a fearsome proposition in next Tuesday’s first leg.

Meanwhile, Thomas Tuchel’s men are a massive 10 points clear at the top of Ligue 1 with two games in hand on the teams below them as they prepare to welcome mid-table Bordeaux to the Parc des Princes, and are also through to the quarter-finals of the French Cup.

However, they needed extra time to beat third-tier side Villefranche-sur-Saone 3-0 in the Cup on Wednesday, three days after seeing their unbeaten league record this season ended in a 2-1 defeat at Lyon.

They were knocked out of the League Cup by struggling Guingamp in the quarter-finals last month, and since then Paris have lost Neymar to a metatarsal injury.

The Brazilian is not expected back until early April, but the worries do not stop there.

Looking increasingly irritated of late, Tuchel admitted after the Cup tie in midweek that some of his squad had played too much football in recent weeks.

Saturday’s match will be their ninth of 2019, and Tuchel has too small a squad to rest certain key players.

“We lack dependable, top quality players,” said the German, offering an explanation for his side’s struggles against lesser opposition.

“We cannot make the mistake of expecting too much from players like (Eric Maxim) Choupo-Moting, who have not played much.”

PSG may be one of the richest clubs in the world, spending the two biggest transfer fees in football history to attract Neymar and Kylian Mbappe in 2017, but the side have not invested enough in other parts of their squad.

The midfield is the greatest concern, even if Argentine international Leandro Paredes made his full debut against Villefranche after signing from Zenit St Petersburg for 47 million euros.

Adrien Rabiot is still frozen out over his refusal to sign a new contract, while Marco Verratti has not featured in three weeks due to an ankle injury.
