Paris Saint-Germain head coach Thomas Tuchel insisted Neymar "cannot do everything" after the star forward failed to score in the Champions League final defeat against Bayern Munich.

Neymar fired a blank as PSG – featuring in their first Champions League decider – lost 1-0 to German giants Bayern in Lisbon on Sunday.

The Brazilian, along with star team-mate Kylian Mbappe, did not score for PSG in the "Final Eight" tournament, failing to find the back of the net in the quarter-finals, semi-finals and final.

Neymar's last 14 shots in the Champions League were all unsuccessful, while he lost 47 per cent of the touches he made against Bayern, per Opta.

But Tuchel backed Neymar – who was in tears post-match – and Mbappe, with the duo leading PSG to a domestic sweep of all four titles in France in 2019-20.

"Neymar has had a great tournament, he cannot do everything," the German boss said.

"Mbappe, it's a miracle that he was with us after sustaining a serious [ankle] injury [in July]."

After the match, speculation emerged that Tuchel could be replaced by former Juventus coach Massimiliano Allegri.

Tuchel has won back-to-back Ligue 1 titles among other honours since arriving in 2018, and the former Borussia Dortmund coach was asked about his future.

"We will see, it is not always the head coach's decision we will talk about all that not only about my contract extension but also about how to rebuild the team," Tuchel told reporters.
