New boss Ronald Koeman has impressed and, according to Ward-Prowse, brought in enough quality to replace what has left.
"It's disappointing to see them go because they played such a massive part in what we did last year, but it's football and people come and go and we've had a number of new signings who have come in, done terrifically well and will fill those shoes comfortably," said the midfielder.
"Football is always changing. There is always people coming and going and as long as we just focus on ourselves as a team and making sure we improve then all the off the field issues won't matter. We just focus on what we do on the pitch."
