Chelsea captain John Terry is still mentally and physically fresh for top-level football, according to interim manager Guus Hiddink.
The 35-year-old played every minute of Chelsea's title-winning campaign last season under Jose Mourinho.
"I must say he looks physically fit but also what is important when you're halfway through a season is that he's very fresh - and I mean fresh in the mind," Hiddink told reporters.
"He's very eager to train every day, to play.
"Normally - it depends a bit on the physical shape and genes - but most of the time when players come to 32, speed is dropping down and everything is more difficult.
"There are exceptions, depending on position as well, but normally after 32 they drop from their top physical abilities.
"Of course one day the body will say 'Hey, slow down a bit'. But I don't see any of that [in Terry]. I've not been asked [by the board about Terry] but these [experienced] guys are very important for Chelsea."
Hiddink's next test is an FA Cup third-round match against Scunthorpe United on Sunday.
