#4 Ruben Dias (SL Benfica)
One of the highly rated youngsters coming out of the stables at Benfica, young Dias has been spoken of in glowing terms and there are already pundits comparing him to the legendary Portuguese centre-back Fernando Couto.
While he shares an innate sense of taking responsibility like Kompany, Dias differs from the great man.
His style of play is more aligned to the cultured style of players like Gerard Pique rather than the thou-shall-not-pass motto of the Belgian he might replace.
The young Dias who just made his first-team debut in Liga NOS last season has become an ever-present for the Eagles. He has at his rather tender age of 22, taken the mantle of leading the defence from the recently retired legend: Luisao.
This will help him adapt quickly to the demands of Guardiola's system. Alongside Laporte and Stones, he would form a formidable, long-term unit on which City can build for the present and future.
Alongside teammate, Joao Felix, Dias is one of Europe's most sought-after youngsters and will not come cheap.
