England coach Trevor Bayliss concedes his squad have been given a reality check by South Africa, less than a month before they open their World Twenty20 campaign.
Bayliss' side were impressive in defeating the Proteas 2-1 in a four-match Test series, but then lost the ODIs 3-2 having been 2-0 up, before losing both T20 encounters.
The second of those T20 defeats was particularly harrowing, as South Africa reached their target of 172 with more than five overs remaining as AB de Villiers and Hashim Amla punished England's bowling attack.
England's first World T20 fixture comes against West Indies in Mumbai on March 16, and Bayliss admits his young side have to learn fast.
"Yes [it is a reality check], certainly. It shows we've still got a lot of hard work to be done.
"We've had some good results, but it's a reminder to people back home in England that this team is still a developing one.
"We've had some good performances, and there's a lot of potential there. But potential never won anything... we've got some hard work to do.
"I think the expectation the players have put on themselves is why they are so disappointed when they play badly. It may be that extra pressure they put on themselves that they've got to get over.
"We'd obviously be better off going to the World Twenty20 with a couple of wins under our belts. But in Twenty20, the momentum of games can change very quickly - and so can results.
"I don't think it really matters all that much. We're three weeks away yet from the first game and have a couple of practice games over there... we're looking forward to them."
