Hello @Alexandru Gangea

Welcome to the Atlassian Community!

In order to mention a Jira ticket in a Trello card and display this information in the related ticket, you must install the free app Jira Power-up for Trello:

Jira Cloud Power-Up for Trello 

Also, the link is only visible in the old issue view of Jira. These would be the exact steps:

1. Install the application above and follow the steps to integrate your Jira and Trello
2. Then, copy the link of your Jira issue and paste it in any part of your Trello card (Description, comment, etc):
   
3. Navigate back to your Jira issue > Click in the three dots button > Turn off new issue view > unflag the lab feature in the page displayed:
   

Once you do the steps above, the issue view will display the mentioned link as displayed in the screenshot. Additionally, we have the following feature request created to display the Trello link in the new issue view of Jira:

'mentioned in' section related to Trello is missing in the new Jira issue view
