The two defensive veterans haven't been on speaking terms since an incident concerning Ferdinand's brother Anton in 2011, but that didn't stop Rio lavishing praise on his former England partner.
"It's no secret that me and John Terry are not the closest of mates,” Ferdinand said in the Sun. “But just because we no longer get on does not mean I've lost my admiration for him as a footballer.
"His performances for Chelsea this season have been nothing short of outstanding and I'm not afraid to say it. John took the decision to retire from playing for England and had his reasons, but Chelsea are reaping the benefits."
For a large part of each other's England careers, Ferdinand and Terry were partners in central defence. The two were both among the best defenders on the planet in their prime, but were unable to guide England to international glory.
The problems surrounding Terry's clash with Ferdinand's brother led to England boss Fabio Capello's resignation, and ultimately played a part in the ending of both players' international career.
However, while Rio Ferdinand moved back to London for a seemingly final swan song with QPR, Terry has continued to star for league leaders Chelsea, with Jose Mourinho stating last weekend, according to quotes in the Mail, that his captain's performance against Arsenal was Terry's very best.
And Ferdinand has admitted that, despite the differences between the two in recent years, the Blues skipper remains one of the best around.
