#3 Niklas Süle (Bayern Munich & Germany)
Alongside Tah, Süle has for a long time been seen as the long-term successors to Mats Hummels and Jerome Boateng. The former Hoffenheim man stood out for the Baden village team during his 7 years at the team and it was no wonder that big European clubs were after him until he joined Bayern Munich last summer.
Due to his height and German heritage, the 22-year-old has often been compared to his fellow countrymen Per Mertesacker and Holger Badstuber but while these two were noted for their immaculate sense of positioning as a compensation for their lack of speed, Süle is fast for a centre-back and this helps him get back into defensive positions to thwart opposition attacks.
His height and physical strength make him tailor-made for the Premier League as he would not find it difficult coping in the physically demanding environment in England. Despite his young age, he is an excellent marshaller of the backline and would automatically step into Cahill's role as defensive leader and organizer.
The question is not if he will fit into Chelsea as a perfect replacement for Cahill, the question is if a club as well-run as Bayern would want to lose such a player (who has already been earmarked as Hummels' long-term replacement).
If Chelsea were to get his signature, he would cost them something close to what Liverpool paid Southampton for Virgil Van Dijk and given his abilities and growing status, it could prove to be a brilliant decision.
