Rafael Benitez was interviewed about Sky after the victory against Benfica about the difference in winning a world cup trophee with Inter and then leave, just like now winning the Europa League and having to leave:

“There is a difference, Inter had won a treble. I said we needed reinforcements and they didn’t come. Here the team is young and needs to grow. Everyone knew I would leave, but they have worked very hard.”
