Arsenal legend Paul Merson praised Kai Havertz for his composure as the Gunners ran riot against Lens in the Champions League.

Mikel Arteta‘s Arsenal charges were rampant against the Ligue 1 outfit at the Emirates Stadium, with the result a foregone conclusion by the half-hour mark in the match.

Havertz got the ball rolling for Arsenal, scoring in the 13th minute of the match for his second goal in his last two games.

Three more goals followed from Gabriel Jesus, Bukayo Saka and Gabriel Martinelli and Havertz played a part in the third, the one Saka scored.

Havertz won the duel from a David Raya kick, nodding the ball down into Declan Rice’s path.

The midfielder then fed his teammate down the left, whose shot was initially saved well by Samba.

However, Saka was on hand to convert as the ball hit him on the legs and rolled into the back of the net.

Havertz also played his part in a potential fifth ahead of Martin Odegaard’s goal on the stroke of half time.

Saka played in Martinelli down the right of the area, but he fired into the side of the net. Better placement and that would’ve been the fifth.

“It should be 5-0,”Merson said on Sky Sports News.

“Havertz is so calm on the ball in the move. Martinelli just has to roll it across the goal and Jesus would have an easy tap in.”
