"The players are uneasy; there was a lot of chatter at the breakfast table", SA's team manager, Mohammed Moosajee, told reporters in Leeds, where the first one-day global will be played on Wednesday. "They are a well-balanced team, we understand that. It is important for myself, the coach and team manager to convey that type of message to the players and to keep them focused on the task".
A three-match contest between the sides starts with a day/nighter at Headingley on Wednesday, with the series given added spice by the fact it acts as a warm-up for next week's Champions Trophy tournament in England and Wales.
Morgan's side have enjoyed a decent run since they left South Africa early past year where they let slip a 2-0 lead to lose 3-2, winning five of their six series, 15 of their 19 matches and consolidating fifth spot in the ICC rankings. It is important for me to make sure I am feeling physically and mentally healthy going into every game I play and that is what I chose to do.
"M ake no mistake, if this had happened in any other country in the world that is the first question people would ask. We are comfortable with the advice we get from our security team". Is the series at risk? With Alex Hales and Jason Roy, they have some unsafe players who will be eager to gain form and carry that into the Champions Trophy. "If the intelligence information tells us something else we would obviously have to reconsider". "But when things go wrong, they go wrong anywhere in the world". When it happens so close to home it hits you a little bit harder. "It emphasises that life is very short and can be taken away at any stage". "It doesn't get any better than playing in England before a big tournament against the hosts", de Villiers said. There was a lot of chat in the breakfast room this morning.
"It was a big shock and what happened is sad and unfortunate", De Villiers said.
Ahead of today's 50-over opener at Headingley Morgan said: "It is really exciting for us to be starting our prep in this series against one of the best sides in the world, one full of accomplished players and experienced players".
"We operate on advice from our tournament security directorate - in conjunction with the European Central Bank and relevant authorities - to ensure we have a robust safety and security plan for both tournaments", an ICC statement read.
Morgan, meanwhile, has confirmed Moeen Ali will return to the team after being dropped for the two ODIs against Ireland earlier this month.
The summer schedule began with two one-day internationals against Morgan's native Ireland, games which key trio Ben Stokes, Chris Woakes and Jos Buttler were excused in favour of extending their stay at the Indian Premier League.
Mark Wood and Liam Plunkett are expected to both retain their places in the seam attack, with David Willey set to miss out.
