This week Bleacher Report is taking on the mammoth task of attempting to name Chelsea's top 50 players of all time.
Using the hashtag #CFCTop50 on Twitter or the comments section from our news story covering the top 50 (published on Monday), we're encouraging fans to get in touch with their views on who should make the list.
We'll be publishing all 50 players on Sunday, Sept. 22, but in the meantime, we thought we'd whet the appetite with our list of the Blues' top five central defenders.
Now, there have been some fine warriors in the centre of defence for Chelsea down the years. Some who have defined an era and others who have captured the imagination.
The likes of Frank Leboeuf and William Gallas are just two notable names that spring to mind for players who missed out, but whittling it down to just five proved a difficult task, and for one reason or another, they narrowly missed out.
Anyhow, without further ado, sit back and celebrate the Stamford Bridge careers of five Blues legends.
If you you think we missed someone out, or worse, simply got it wrong, let us know who your top five central defenders would be in the comments section below.
