As of my last knowledge update in January 2022, I don’t have specific information on recent transfers or developments in football, including the situation involving Kader Mangane and Sunderland. Transfers and negotiations can evolve rapidly, and the details may have changed since then.
However, based on the information you provided, it seems that Kader Mangane, who has been linked to Al Hilal since the previous summer, is now potentially considering a 6-month loan to Sunderland in the Premier League. If he is indeed expected in Great Britain to negotiate his salary and undergo a medical examination, these are typical steps in the process of finalizing a player transfer.
It will be interesting to see how this situation develops and whether Kader Mangane joins Sunderland for the second half of the Premier League season. Football fans often look forward to transfer news and how new additions may impact a team’s performance. If there have been any updates since my last knowledge update, you may want to check the latest sports news or official announcements for the most current information.
