There's only one centre-back on the 23-man shortlist - Paris St Germain defender Thiago Silva.
So what about Hummels? The Germany star was the bedrock of a Dortmund defence that formed the solid formation for their march to the Champions League final.
Silva may have won the Ligue 1 title with PSG, but the Bundesliga is arguably a stronger league and Dortmund finished second only to the all-conquering Bayern Munich.
If any defender had an outstanding individual season other than Silva, it was Hummels.
