Manchester United have signed Anthony Martial to a five-year contract that keeps him at the club until 2024.

"I am loving my time at this club. From the day I joined I have been made to feel part of the United family and I have been incredibly humbled and overwhelmed by the warmth and love of our fans, who continue to amaze me with their support," said Martial.

Ole Gunnar Solskjaer praised Martial's ability. 

"Anthony is one of those naturally gifted players that any coach would love to work with. For a young man, he has a good footballing brain. When coupled with his exceptional talent, that makes for a player with an exciting future ahead of him."

Leonard Jardim returned as Monaco manager after the club sacked Thierry Henry.

Henry originally replaced Jardim, who was sacked by the club in October.

Henry wished the club well in a goodbye statement.

“I would particularly like to thank (vice president) Vadim Vasilyev and (director) Michael Emenalo, who afforded me this opportunity at my boyhood club, and of course the fans and staff who have given me such a warm reception during my tenure. I sincerely hope that my successor will now take AS Monaco on to greater strengths and I wish them all the success for the future, starting with a win in Dijon and lifting the cup and getting us back into Europe!”

Huddersfield Town have appointed Jan Siewart as their new manager, replacing David Wagner. 

The 36-year-old Siewart comes from Borussia Dortmund II's, and is expected to continue the club's high-pressing style.
