Lendl parted company with Andy Murray in March after he helped the British No1 win his two Grand Slam titles.
Berdych took to Twitter on Monday to reveal that he had spoken to Lendl – but the 54-year-old is “too busy” to work with him.
Berdych said: “I had a great time talking about tennis with Ivan Lendl today. Result? Ivan would like to help me, but he is too busy…”
Lendl recently said that he does want to return to coaching, when the right opportunity comes along. He told BBC Sport: “I’ve had a lot of enquiries. Eventually, when the time and situation are right, I enjoyed it enough that I will do it again.”
