Levi Colwill reveals he enjoys Enzo Maresca's 'crazy' training sessions as Chelsea star admits Italian's tactics are 'demanding mentally'

Colwill has been fully immersed in the intense pre-season preparations under the guidance of new head coach Maresca. The 21-year-old defender has proven to be a vital component of Maresca's plans, having clocked the fourth-highest minutes among Chelsea players during the six pre-season fixtures. This heavy involvement signals the trust Maresca places in Colwill as the team gears up for the upcoming Premier League season.

Colwill has showcased his versatility on the pitch, performing in multiple defensive roles. Notably, he anchored the defence in the heart of the backline during the match against Inter Milan. Additionally, he demonstrated his adaptability by operating as a left-back but also transitioned into a left centre-back position in a three-man defence, depending on the tactical demands of the game. This flexibility is a testament to Maresca's tactical philosophy which the English defender is enjoying daily at Cobham.

"The gaffer plays similar to a chess game," Colwill explained in an interview with Chelsea's official website.

"I always need to be aware of where I am on the pitch and how I can help the team move up the pitch. That is the main thing. The level of concentration is crazy compared to other managers, I would say. I enjoy it and it can tap into my strengths. He’s been really good with me personally and everyone in the team. I’m really understanding the way he wants to play very fast."

One of the most significant aspects of Maresca's coaching, as noted by Colwill, is the hands-on approach and attention to detail. He believes that the Italian's commitment to providing equal time and effort to every player has fostered a positive environment within the squad which will help them rediscover their lost glory.

"'The players are much more comfortable with the system," he said. "You can tell by the patterns of play and doing what the gaffer wants, which is working. We are creating opportunities to score. As a coach, he is very hands-on. He gives every player the same amount of time and effort. Everyone can see it on the pitch, the difference."

Colwill is aware that the trust Maresca has placed in him is a significant opportunity, and he is eager to repay that faith by consistently performing at the highest level when the competitive fixtures begin with a clash against Manchester City on Sunday in the Premier League.
