The Finn is today celebrating reaching the 2020 Euros, though goals have dried up for him in the Premier League.
But Farke told Kicker: "He works hard and is a great guy in the locker room for the whole team. He thinks more about the team than his personal goal statistics, and he works a lot for the team in the pressing game.
"He also fits in well with our technical qualities. He is active in the combination game, always playable and very flexible in his movement patterns. Pukki is a top attacker in many parameters and we are very happy to have him."
