Despite a series of dreadful displays from Ivanovic this season, Mourinho has kept faith with the right-back.
The effect has been twofold: one, Chelsea are leaking goals at a rate never seen in the Roman Abramovich era, and two it looks like favouritism when a player so patently out of form is still being played, while the likes of John Terry have been dropped.
After the 3-1 defeat to Southampton in which Ivanovic was routinely beaten by Sadio Mane and Dusan Tadic, Mourinho insisted he would not be rushing to drop the Serb.
