Mikel Merino has expressed that Arsenal's training methods are unlike anything he has experienced before, highlighting both the physical and mental challenges involved. After making his debut in the recent 2-0 Champions League victory over Paris Saint-Germain, the Spanish midfielder shared his insights on the club's rigorous training regime. Merino, who recently recovered from a shoulder blade fracture sustained during his first training session with the team, described his initial month under manager Mikel Arteta as transformative. He noted that the intensity and attention to detail in training have reshaped his understanding of football. This sentiment mirrors the experience of Declan Rice, who also remarked on the demanding nature of training after his transfer from West Ham last summer. Having signed from Real Sociedad for £31.6 million at the end of August, Merino faced a frustrating wait to make his debut. However, he finally took to the pitch as a substitute in the 64th minute, joining Rice in the midfield. His comments reflect a growing appreciation for the club's approach, which emphasizes relentless effort and focus.
