John Aldridge was approaching 36 when he went to USA 94 on international 13 goals from 60 odd caps....
Bizarre that Doyle, not yet 31, already has 13 goals from 57 games, this in spite of his much reported lack of goals of late...
Conceivable he could level with or overtake Aldridge's tally of 19 and maybe even finish second highest goal scorer - Niall Quinn there at moment on 21 goals.
