West Ham striker Teddy Sheringham says he is keen to continue playing for as long as possible - despite turning 40 during the coming Premiership season.
He could find himself playing alongside 20-year-old striker Petr Mikolanda, who has signed after a trial period and names Sheringham as his childhood idol.
"Why am I playing? Probably because I don't fancy having grey hair yet. That makes me carry on," said Sheringham.
"As soon as you come out of playing it is a stressful time 24 hours a day."
West Ham are keen to sign another striker, despite buying Czech U21 international Mikolanda, but Sheringham is eager to try and earn a regular first-team spot.
"For me the top flight is the only place to play. It is where all the business is. So, of course, it is fantastic to be back," he said.
"Can I still play a full part at this level? You are asking the wrong man. You should ask the manager, but I am looking forward to it."
Hammers boss Alan Pardew said the club will make sure they get the best out of Sheringham, despite the increased physical demands of the Premiership.
"We will make sure Ted is looked after," he said.
"He has got a terrific staff around him and sometimes it is not just how hard you work but how well you recover."
