The English striker spent two seasons at Ibrox after moving north from Wigan Athletic during Mark Warburton’s reign.
Waghorn was important as Rangers won promotion to the Scottish Premiership and then had a strong first season in the top flight too.
He scored 28 goals in 36 appearances during his first campaign before hitting 16 in 41 during his second.
But Waghorn was offloaded to Ipswich, in a deal worth less than £1m, last summer after Pedro Caixinha deemed him surplus to requirements.
Since then, he’s hit 16 goals and made 11 assists in 44 games – and that was enough to persuade Frank Lampard’s Derby to spend £5m to sign him today:

That is a big move for Waghorn as Derby appear very serious about competing for promotion to the Premier League in Lampard’s first season as a manager.
As for Rangers, they may be kicking themselves for allowing Waghorn to leave at such a low price.
