"In England, you have to be tougher," said the Argentina international. "The teams are more physical and harder, especially in midfield and there are plenty of tackles flying in. That's how I like to play and it suits me.
"But in the Champions League, I get booked too often. It doesn't seem to happen too much in other games.
"I just love playing in these big cup games with Liverpool. I went from not playing at West Ham to being involved in some huge occasions.
"It doesn't get any better than this. Hopefully, there are a few more great days and nights around the corner.
"I'm glad I came to England. When a footballer comes to the Premier League he automatically turns into a superior footballer.
"I'm a much more simple player now. I've understood that if I don't pass within one or two touches I get closed down.
"Football is so physical here - the quicker I get rid of the ball the less I get knocked around!
"I pass and move and only get involved in a clash with another player when it's absolutely necessary."
Mascherano, 23, aims to secure a permanent move to Liverpool in the near future.
The Reds have already verbally agreed a four-year contract with him.
And the 20-cap star added: "The sooner things get sorted out with Liverpool the better.
"I want to be settled and kill myself on the pitch so the team wins lots of games."
