Rio Ferdinand has questioned Carlo Ancelotti's 'massive call' to drop Antonio Rudiger for Eder Militao on Wednesday, as Real Madrid prepared to take on Manchester City in their Champions League semi-final second leg.
Rudiger, deputising for regular first-choice centre-back Militao last Tuesday, put on a defensive masterclass to stop City talisman Erling Haaland as the reigning champions carved out a crucial 1-1 draw at the Bernabeu.
The German matched Haaland for speed and physicality throughout the contest and forced the free-scoring Norwegian into a rare quiet game on the big stage.
However, despite his fruitful display last week, Ancelotti opted to keep faith in first-team regular Militao upon his return, dropping Rudiger to Real Madrid's bench.
When asked to explain Ancelotti's thought process, Ferdinand admitted on BT Sport: 'I actually don't know. I finished watching that game (the first leg) thinking: "Have we finally seen a defender who can deal with Haaland?"
'Sometimes you think to yourself, if he's got his number, you have to go with your instincts. Ancelotti's gone with someone he knows, who's tried and tested, and obviously they won it last year with Militao.
'He's been integral to everything that's been good about them in the last season or so. So he's gone back to what he knows.
'But I think it's a massive call. And if it goes wrong, that's something where the media in Spain will be honing in on.
'How can you drop someone who's done so well against their talisman?'
