Fan had to tell Al Nassr goalkeeper about a backpass in the first minute of their match

Al Nassr goalkeeper Waleed Abdullah was almost the victim of an embarrassing mishap during the first minute of his side's Saudi Pro League clash against Al Taawoun on Friday.

Al Nassr welcomed Cristiano Ronaldo back to the fold after he missed their 2-1 defeat to Steven Gerrard's Al Ettifaq through injury.

And with Sadio Mane, Marcelo Brozovic and Anderson Talisca all in the side, manager Luis Castro fielded an attacking line-up to take on Al Taawoun, who drew their opening match of the season.

But they had defensive issues to worry about early on, when a defender passed the ball back to goalkeeper Abdullah.

The problem, however, was that the shot-stopper was walking back to his goal - with his back to play.

As he looked towards the crowd, one fan began repeatedly shouting Abdullah's first name in attempt to alert him to what was happening behind him.

Thankfully, the ball was trickling wide of the post, but the 37-year-old quickly realised that he needed to act and stopped it from going out for a corner - much to his own relief.

Unfortunately for Abdullah, however, he ended up picking the ball out of his net twice later in the match.

Goals from Leandre Tawamba and Ahmed Bahusayn gave Al Taawoun a surprise away victory, with Al Nassr still yet to pick up their first point in this season's Saudi Pro League.

Al Ahli and Al Ettifaq are the only two teams to have won both their opening games, although Al Ittihad and Al Hilal are among the sides to have an 100 per cent record from their only fixture played.

Former Liverpool star Roberto Firmino netted a hat-trick for Al Ahli as they beat Al Hazem 3-1 last week, with fellow former European stars Mane, Cristian Tello and Riyad Mahrez among the others to have already got off the mark this term.
