Martinez and Antonio Candreva decided the result with a goal in either half.
He said, “We were coming off the defeat to Barca, having played very well at Camp Nou. We lost to Juve, then did well to beat Sassuolo, even if we ended that game with the wrong approach.
“It was important to get back to winning convincingly and that's what we did this evening."
He scored a great goal, but also saw his penalty saved.
“To be honest, I wanted to shoot the other way, but I changed my mind at the last second. Fortunately, Antonio (Candreva) scored the second late on and we were able to get a more comfortable result.
“We have to keep training hard, continue to improve and follow everything Antonio Conte asks for. If we do that, it'll be tough for opponents to play against us."
