Heskey admits he is disappointed to be unavailable for England's Euro 2008 qualifiers against Estonia and Russia, having made a successful return to the team last month.
But he has backed Owen and Rooney to fire England to six points from their next two games.
He explained: "I'm delighted to see Michael back - the last thing he needed was another long lay-off.
"England need him because at the minute, strikers are dropping like flies, but Michael and Wayne can work together up front - they have before.
"They are international class players who play in the Champions League, so they should be good together."
