The English prospect was sidelined over the course of a month owing to a virus attack.
Clarke was subbed off in the last month’s game against Boros as soon as he fell to the ground.
After recovering by leaps and bounds, the winger was given little playing time in the last week’s defeat against Sheffield United.
Nonetheless, Marcelo Bielsa was excited to see the return of Clarke.
Ahead of the game against Millwall this weekend, the English youth was at his usual best in the training camp.
The 18-year-old scored a belter of a goal with his so-called weak foot and with much elegance.
Clarke shot the ball from outside the box after a clumsy first touch leaving goalkeeper speechless.
The fans took to Twitter to express their praises on the awe-inspiring effort.
