Messi’s 700th finally came early in the second half when the Argentine beat Oblak from the penalty spot with a cheeky chip to give his team a 2-1 lead and become just the seventh player in football to reach that mark.
Atletico drew level in the 62nd minute with yet another penalty, Saul converting his second of the night after Yannick Carrasco was tripped by Nelson Semedo, who had just drawn the foul for Messi’s penalty earlier in the half.
The 26-year old still managed to have one shot on target and two off target, while his six dribble attempts were successful.
He made five tackles, won 12 of 20 ground duels and was also solid in the air, winning four of five aerial duels.
Arsenal has been tipped to be the next destination of the 27-year-old combative midfielder.
