Jamie Carragher was a superb servant for Liverpool during his playing days.
The Bootle-born defender made his debut in 1997 at the age of 18.
He would go on to be a mainstay for the club all the way up until his retirement in 2013.
In that time frame, he made 737 appearances in all competitions for the club, scoring five goals.
Unfortunately, he would not win a Premier League title but, he did help the club to 11 major titles, including the Champions League in 2005.
Since retiring in 2013, many consider him to be among the defenders in the history of the Premier League.
But where exactly does he rank?
Carragher is celebrating his 41st birthday today and Goal asked their followers on Twitter where they think he ranks among the Premier League's best ever defenders.
Gary Neville, Carragher's colleague at Sky Sports, saw the question and felt the need to respond.
And he just had to make fun of him.
Neville replied: "He was one of the best. We couldn’t do without his own goals at United!"
That is gold from Neville.
Of course, Carragher has the second most own-goals in Premier League history, having put seven in his own net during his career.
That is three more than the amount of goals he scored in his Premier League career.
It's no surprise that his answer quickly went viral, having attracted 4.8k retweets and 32k likes.
Carragher also saw the question and also produced a superb answer.
He tweeted: "2nd behind VVD!"
It seems neither of them took the question very seriously.
When Carragher was being serious, he said that John Terry is in fact the Premier League's best ever defender.
Carragher named Terry as the best after he announced he would be leaving Chelsea in 2017.
Writing for the Daily Mail, Carragher said: "My type of defender, someone who would put his body in front of anything to stop a goal. It should not be forgotten, though, what a great footballer he is and I know from playing alongside him how effortlessly he could ping a 60-yard pass with his left foot.
"During Jose Mourinho's first spell at Stamford Bridge, with Terry commanding in the middle and Petr Cech in goal, it felt almost impossible to score against them."
