Slightly strange that neutral umpires are being used only from the 3rd ODI onwards. Perhaps this signals that from May the appointment of neutral umpires will be back to how it was pre covid?
To further back this up, I’ve read in the times of India that Nitin Menon has been appointed to the 3rd and 4th tests of the Ashes. The article also states that he’ll be joined by Dharmasena in the 3rd test and Joel Wilson in the 4th test, with Menon also being TV umpire in the 5th test.
