Used to being overshadowed by Kylian Mbappe at club level and Son Heung-min on the international stage, Paris Saint-Germain's Lee took centre stage at Jassim Bin Hamad Stadium.

While Son missed a golden chance late on and was also booked for diving, Lee scored two picture-perfect goals to get South Korea off to a winning start in the competition the country has not won since claiming back-to-back titles in 1956 and 1960.

Not that he was comfortable with the spotlight.

"I would just like to say and highlight that it is not about individual performance. It's not just about my two goals. All the goals we score are very important for the team," he said after the Group E match.

His coach Jurgen Klinsmann was also restrained in his praise.

"If you score two in the opening game of the Asian Cup for us you deserve to be man of match and [it was] a very good performance. But I have to keep him on the ground every day," he said with a smile.

The game was tied at 1-1 when Lee took control, giving South Korea a 2-1 lead in the 56th minute with a left-footed shot from around 30 yards.

He was equally clinical as he scored his second goal 12 minutes later when showing sharp footwork and curling the ball into the bottom corner.

Hwang In-beom had given South Korea a first-half lead, but Bahrain equalised six minutes after the break through Abdullah Al Hashash.

Jordan sit top of Group E on goal difference after a 4-0 win over Malaysia.

Mahmoud Al Mardi and Mousa Tamari scored two goals each in the match at Al Janoub Stadium.

Jordan raced to a 3-0 half-time lead, with Al Mardi on target twice and Tamari scoring from the spot. The latter, who also had a goal disallowed by VAR, doubled his tally in the 85th minute.

In Group D, Iraq moved level with Japan on three points thanks to a 3-1 defeat of Indonesia.

Goals from Mohanad Ali, Osama Rashid and Aymen Hussein secured victory at Ahmad Bin Ali Stadium, while Marselino Ferdinan netted for Indonesia, who are making their first appearance in an Asian Cup in 16 years.
