Bayer Leverkusen boss Roger Schmidt criticised Tottenham target Son Heung-min after he sat out their crucial Champions League qualifier.
News of Tottenham's interest in Son broke on Wednesday, with the South Korea forward skipping training as a result ahead of the second leg of Leverkusen's play-off against Lazio.
The German side turned around a 1-0 deficit to progress to the group stage courtesy of a 3-0 win, but Schmidt was not happy about the unnecessary distraction.
"Son is a great player who has actually got not really good advice," Schmidt told television channel Sport1.
"He has decided to do something that was not so nice for us as a team. It was not ideal. But it was even more important that we get into the Champions League, but we had to deal with it."
Son's team-mate Hakan Calhanoglu backed up his manager's comments, adding: "I think it's just a pity that he is ill advised by his dad or agent, just before so a game like against Lazio this did not have to be."
Calhanoglu also revealed he had called and texted Son when he did not appear for training, but did not receive a response.
He added: "He is a great kid. I look forward to any event, if he comes back and said goodbye to the team, if he goes away, we definitely lose a very good player."
