The club captain signed a 'long-term' contract extension at Anfield on Thursday, with boss Kenny Dalglish also hailing the 31-year-old's recent return from injury
Comolli was speaking after Gerrard’s decision to extend his contract at Anfield for the foreseeable future after penning a ‘long-term’ deal on Thursday.
He told the club’s official website: "Everybody says he's the best player this country has had for the last 20 years. I think that's quite unanimous.
"It's a great day for the club, for the fans, for the manager and for everybody because, as I have said in the past, it's a sign we want to keep our best players here.
"Because he is the captain and because of everything he has done so far it's an even better feeling.”
Meanwhile, manager Kenny Dalglish is delighted that the 31-year-old has committed his future to Liverpool despite the England international’s recent struggles with injury.
The contract was signed hours after Gerrard guided his team to a 1-0 victory over Manchester City in the League Cup semi-final first-leg, scoring a first half penalty to give the Merseysiders the advantage in the tie.
Dalglish added: "For us, for Steven and for everybody connected with football club it's fantastic news.
"We're delighted for him and are looking forward to him getting back to full fitness and working hard for us and with us.
"He's been a fantastic servant to the football club."
