McCarthy was sacked by in February and the club have managed just a solitary point under interim boss Terry Connor. Wolves currently sit bottom of the league, six points from safety and Jarvis has conceded that the squad haven't reacted well to the Irishman's sacking.
“It was hard when Mick got sacked. He brought pretty much everyone who was in the squad to the club,” he told The Daily Mail.
“He had been a fantastic manager and really brought everyone’s game on.
“He worked hard with everyone on the training pitch and I thank him for everything he’s done.
“I’m still in touch with him. We all saw him the day he left. We all went in individually and spoke him.”
Jarvis broke into the England set-up while under the management of McCarthy and the winger has revealed he is working hard in Wolves' relegation scrap to try and secure a spot at Euro 2012.
He continued: “I’d love to go [to Euro 2012]. I need to make sure that I keep playing well. Week in, week out, keep performing.
“I got a taste for it once I got picked. I’m working extremely hard to make sure I play well for Wolves and if I do that maybe I can get back in there.”
