You mean, like to van Dijk, or Forster, for example?
You can count on one hand the teams that can keep all their players.
We might have lost Wanyama and Mané, but we've also improved on the quality of players we've been able to keep hold of.
We've also kept hold of Wanyama, Schneiderlin and Mané a season longer than we once would have, which has given us two seasons of qualifying for Europe. That'll let us attract better replacements for those players.
We won't carry on improving season on season forever, but we definitely have the structures in place for the Club to improve over time.
