Cristiano Ronaldo is one of the best players in world football and will take his place among the finest performers ever to have pulled on a Real Madrid shirt when his days at the Bernabeu come to an end.
While it remains unlikely that the Portuguese international will leave los Merengues any time soon, you can never be chastised for planning ahead.
Here are five players Jose Mourinho could target as the next Cristiano Ronaldo.
Bernard is a pacey, skillful winger currently plying his trade for Atletico Mineiro in the Brasileiro Serie A.
At just 20 years of age, he's still a very raw prospect, and his short stature attracts the typical apprehension as to whether or not he could cut it in the top European leagues.
That didn't stop Lionel Messi, and it won't stop Bernard either. He's recently earned his first full international cap under Mano Menezes to cap of a year of excellent progress.
Erik Lamela is having quite a season over in Italy's capital city.
The AS Roma forward came very, very close to breaking Rodolfo Volk's record of most goals in consecutive games this month but fell just short of the mark despite an excellent display.
The Argentinian—who is still just 20 years of age—is one of the few positive aspects left over from a torrid Luis Enrique reign at the Giallorossi, performing well on either flank or even in a false-nine role.
If the former River Plate youth product continues his rapid progression, he'll be hounded out by a heavyweight in no time.
Real Madrid have experienced first-hand what Mario Goetze can do to even the very best of defences.
The German international is inventive, capable of the spectacular and remains modest in the face of publicity. His movement, ball skills and shooting abilities would see him walk into any team in the world.
Stephan El Shaarawy has scored 12 goals in 17 appearances for a struggling AC Milan side.
He excels as an inside forward operating from the left or right side, stepping up to fill the void of goals left by Zlatan Ibrahimovic this summer.
The last thing Massimilano Allegri will want is to lose his new go-to guy, but the Rossoneri now have an established track record of relinquishing their most prized assets.
Viktor Fischer is a world-beater waiting eagerly for his big chance, but Frank de Boer is doing the right thing by moderating his first-team exposure at Ajax.
He's heavily involved in the Danish youth team setup and he, along with Christian Eriksen, will carry their nation's hopes on their shoulders for years to come.
Fischer operates in a slightly different way to Cristiano Ronaldo in regard to the amount of shots he takes, but he is certain to become one of the premier left-siders within five years' time.
His passing, crossing, speed and trickery are all assets to be admired.
