Speaking at the European Parliament on Tuesday, Ferrand slammed EU's policies regarding Turkey.
"You invited Turkey to the negotiation table which will never produce any results and wanted to exchange migrants in return for EU membership" Ferrand said and added that the European people do not want EU's "project of disaster" and that the block "went astray."
"Sick man of Europe" is a term which initially used to refer to the Ottoman Empire in the mid-19th century at the time of economic crisis, but is occasionally used for other countries experiencing difficulty.
Ferrand continued by saying that Turkey is a great country with a great nation and deserves more than the bloc's proposals, while he criticized the EU for wasting Turkey's and its own time.
The MEP's comments were made on the same day Germany announced that it would put arms exports to Turkey on hold, even though both countries are NATO allies. German politicians had also included dropping Turkey's EU negotiations as part of their election campaigns, to the dismay of Ankara.
European Neighborhood Policy and Enlargement Negotiations Commissioner Johannes Hahn also highlighted that Turkey is a "key" partner of the European Union.
"We are partners, it is a tough partnership but we cooperate on many fundamental issues" Hahn told the EP session.
The commissioner noted that both Europe and Ankara have highlighted the urgent necessity of changing the course of events.
Romanian MEP Cristian Dan Preda noted that it is the third time this year that the EP discusses EU-Turkey relations and that they need to make a decision soon.
He said that the bloc needs to figure out what they will do if they scrap Turkey's accession and what goals they will have as EU.
Meanwhile, German MEP Knut Fleckenstein said that Chancellor Angela Merkel's calls to stop Turkey's accession process did not receive any support, while MEP Renate Sommer said that the bloc's stance could have been different if they were dealing with another country.
"We can't do anything against Turkey, which makes the EU a laughing stock" Sommer said.
French MEP Marie-Christine Vergiat also criticized Germany for politicizing Turkey's EU accession and exploiting it for their election campaigns.
In July, the European Parliament adopted the annual report of Turkey rapporteur Kati Piri, suggesting the suspension of accession talks with Turkey.
Relations between Turkey and Europe have been stalled by many issues, including the failure of the EU to grant visa liberalization for Turkish citizens as promised and EU's indifference to the coup attempt and terrorist organizations attacking Turkey.
The EU and Turkey signed a refugee deal on March 18, which aimed to discourage irregular migration through the Aegean Sea by taking stricter measures against human traffickers and improving the conditions of nearly 3 million Syrian refugees in Turkey.
Although Turkey fulfilled most of the criteria, differences between Brussels and Ankara on anti-terror legislation have forestalled the visa-liberalization deal.
Ankara criticized the European Union's stance on the PKK terror group and FETÖ, saying EU states are turning a blind eye to the terror attacks against the Turkish state and its people as well as the activities of the group within the borders of the EU.
