Howe said: "I admire them tactically; I admire them physically.
"A lot of credit must go to Ange (Postecoglou) for the job he has done and the philosophy he has implemented. I think they have played very well this year."
On last season's 6-1 win, Howe said: "I have had it rarely in my career when everything falls your way.
"It can be something coming together at that time. We were confident and there was a good rhythm in the team. Of course you work to have days like that again."
On last week's win at Fulham, he added: "It wasn't a great performance, but we were dogged and determined.
"I thought it was a big step forward, not playing too well but finding a way to score and win the game. We haven't been able to do that enough this season - find a way to win games like that."
