Conor Gallagher insists his Chelsea departure was not due to him lacking the technical qualities to play Enzo Maresca's preferred possession-based style of play. (More Football News)
Gallagher joined Chelsea at the age of six and progressed through the ranks before making 95 senior appearances for the Blues between 2019 and 2024.
He captained the side regularly under Mauricio Pochettino last season as skipper Reece James battled a series of injuries, only to find himself out of favour when Maresca replaced the Argentine.
Gallagher sealed a £34million move to Atletico Madrid in August, amid questions around his suitability for the patient style of play favoured by former Leicester boss Maresca.
Gallagher started 37 of Chelsea's 38 league games last season, more than any of his fellow Blues midfielders, completing 1,766 of his 1,930 attempted passes with an accuracy of 91.5%.
That latter figure was the best recorded by any Chelsea midfielder in league action, ahead of Moises Caicedo in second (90.8%).
However, when those stats are adjusted to per 90 minute values, Gallagher ranked third among Chelsea midfielders for passes completed (50.7 per 90) and successful passes in the opposition half (28.56), and fourth for passes completed in the final third (15.67).
He does not believe the narrative that he was unable to fit into Maresca's engine room is a fair one, however, saying: "I don't think that's true.
"Last season I had a good season with Chelsea and you could see that by Pochettino playing me every game and showing his trust in me.
"The fans appreciated what I did on the pitch. I'm very grateful for all of that and very thankful to the fans, and very thankful to Pochettino for giving me that platform to go and express myself and show the best version of myself at Chelsea.
"Chelsea make their own decisions and they've brought in some top players on long contracts. That wasn't the situation with me but what happened is good for everyone."
Gallagher has helped his new club make a positive start to the new campaign, with Los Colchoneros sitting third in LaLiga – level with rivals Real Madrid – with eight points from four games.
Asked about his first interactions with new boss Diego Simeone, Gallagher said: "He was very welcoming and it was, 'ready to get to work?', basically.
"That's what he's like, that's his character; he just wants everyone to work as hard as possible, to prepare for each game and to win – and that's perfect for me."
Gallagher will hope to feature for England when they take on the Republic of Ireland in their Nations League opener on Saturday, in their first game under caretaker boss Lee Carsley.
