England captain Eoin Morgan said there was nothing untoward about a new system of signals from analysts in the dressing room used to send messages to him on the field during limited-overs internationals.

“It is 100 per cent within the spirit of the game,” he told a news conference on Thursday as England looked ahead to the start of their three-match ODI series versus South Africa at Newlands on Friday.

The system was used as England swept the T20I series against the Proteas with team analyst Nathan Leamon placing a series of large numbers or letters on clipboards that were visible from the field and were meant to help Morgan in his decision-making.

“There is nothing untoward about it. It’s about maximising information we are taking in and measuring it against things, like the coach’s recommendation or the data,” Morgan said. “There has always been constant communication, verbal or physical, from the change room to the field to help improve my decisions as captain.”
