Paul McGrath confesses he has split loyalties between Manchester United and Aston Villa.
United host Villa today in the Premier League.
McGrath wrote for the Sunday World: "Do I lie awake looking back on my career do I see myself in a Manchester United or Aston Villa jersey?
"It's a question I don't have a definitive answer to, if I'm being honest, and that's why my loyalties will be divided when the United welcome Villa to Old Trafford on Sunday.
"You could say I learned about the football business at United and went on to play my best stuff in a Villa shirt, after a few people had written me off.
"The way I left United - with a few at the club suggesting I was finished at the top - ensured I was highly motivated to prove them wrong at Villa.
"And it's fair to say I did just that, as I was PFA Player of the Year in the opening season of the Premier League era and I loved my time at Villa Park."
