A politically-framed statement there by Tusk
He's speaking with regards to having Eastern European politicians having a go at the top jobs that were selected over the weekend. As long as the current bureaucracy and establishment is in order, that day will almost certainly never come.
In case you missed out on the selection earlier in the week (subject to approval by the European Parliament still):
European Commission president
Outgoing: Jean-Claude Juncker (Luxembourg)
Incoming: Ursula von der Leyen (Germany)
European Parliament president
Outgoing: Antonio Tajani (Italy)
Incoming: David Sassoli (Italy)
European Council president
Outgoing: Donald Tusk (Poland)
Incoming: Charles Michel (Belgium)
European Central Bank president
Outgoing: Mario Draghi (Italy)
