While the match wasn’t a perfect start for the Colombia international, the 28-year-old showed glimpses of his quality to leave a strong impression on the English striker.
"Díaz did a great job today. We've only had a couple of training sessions together so far, but he seems hungry and lively," Kane told Sky Sport Germany.
"You can tell he's happy to be here. He's playing with a smile on his face. Today you could see how effective he is in the final third, and we'll need him this season – so I'm delighted he's here.
"His English is not too bad. He communicates well with the team. Hopefully his English and maybe his German as well picks up so some of the other players can talk to him as well. But with the coach talking English I don't think he has a problem"
