Dennis Wise is well into his 40th year but he looks and plays like somebody a decade younger.
Since joining Coventry City at the turn of the year, the former England international midfield player has had a profound effect, inspiring the team to 19 points from nine matches.
It remains uncertain if Wise will be playing for Coventry next season - he wants to return to management - but it is clear that he would be welcome at the Ricoh Arena, given his experience and enthusiasm.
Micky Adams, the Coventry manager, is astounded at Wise's fitness levels and seems happy to keep selecting the player. However, Wise is suspended for the next two matches after picking up ten yellow cards.
Wise led Millwall to the FA Cup final in 2004 and feels that his heart is in management, having left the London club with his reputation enhanced. But for now, he is a Coventry player, much to the delight of Adams.
"Dennis's fitness levels are still excellent, although you have to be careful with him because of the work-load in the Championship," Adams said.
"But the statistics show that he is doing as much work as any other of our midfielders. Would I give him another contract?
"It's a question I cannot answer at the moment because Dennis has made it clear that he wants a career in management.
"As ever, there will probably be a few of my colleagues losing their jobs in the summer, so we will have to wait and see.
"However, if he continues to play like he has, he would have presented a compelling case for earning himself one," added Adams.
