Lining-up in a 4-4-2 system, we're looking for inspirational leaders, fierce tacklers and flying full-backs.
From double-winning heroes like Maurice Norman and Peter Baker to the fearsome duo of Graham Roberts and Paul Miller that provided the platform for our tremendous success in the early 1980s, right through to the commitment of Ledley King in the modern era and then Michael Dawson – the barricades have been manned by a series of all-action individuals who gave their all in our cause.
So the big question is - who would you name in your back four?
You can have your say HERE...
To help you make up your mind, we'll run the 12 defenders available in blocks of three, next up - Mike England, Maurice Norman and Michael Dawson.
Mike joined us in 1966, lifted the FA Cup in 1967 and although he missed the 1971 League Cup Final through injury, he then played in both legs of our UEFA Cup triumph in 1972, the League Cup the following year and scored as we lost out over two legs to Feyenoord in the 1974 UEFA Cup Final. Mike went on to make 397 competitive appearances for us - he's 11th in our all-time list - and scored 19 goals.
The defensive rock of Bill Nicholson's double-winning team, Maurice missed just one game in the double season and followed up with the FA Cup in 1962 and UEFA Cup Winners Cup in 1963. He developed into one of the best centre-backs in the game and was a member of England's 1958 World Cup squad before eventually earning the first of his 23 caps in 1962. Maurice played 411 times for us and is 10th in our all-time appearance-making list.
A modern-day leader, 'Daws' was loved by team-mates and fans alike, his all-action, committed style helping us to the League Cup Final in 2008 and 2009 - he unfortunately missed the 2008 final victory through injury - and then his greatest moment, leading the team out in the Champions League in Ledley King's absence in 2010-11, including the 1-0 triumph against AC Milan in the San Siro. Michael joined us from Forest in 2004 and made 324 appearances before moving to Hull in the summer of 2014.
