The Spaniard has had a highly-documented beginning to his Stamford Bridge career, with just one solitary goal from 17 Premier League appearances since his arrival from Liverpool in January.
"When I changed club, I knew it was going to be a slow process, although I didn't expect it to be so long," Torres told ligabbva.com.
"Chelsea is, between the English teams, maybe the least English.
"That's because of the kind of player Chelsea has - an older player, who plays very slow, who has a lot of possession, and that's what the club is trying to change now.
"It's normal that it takes some time; it's not easy to find midfielders because the best are already in the best teams and that's why I said that the arrival of Mata is going to give another pace to the team.
"Daniel Sturridge, who has been ruled out for some matches, is also an incredible player, maybe the one that surprised me the most since I came here.
"In the next matches, you will see another pace, and I hope the midfield will adapt to that pace. That is what you need in the Premier League. If not, then the teams don't work.
"When the team will start to get the ideas of the new coach, about paced and vertical football, it's going to be very good."
