Newcastle United manager Alan Pardew admits he is anxious about star midfielder Moussa Sissoko.
The 25-year old Frenchman has been impressive for the Magpies this season which has attracted the interest of both Arsenal and Chelsea.
There are suggestions that both the Gunners and Blues will make a move for Sissoko in January which has Pardew worried that he could be the next Toon ace to leave St James' Park after Yohan Cabaye and Mathieu Debuchy's recent departures to Paris Saint-Germain and Arsenal respectively.
"He is playing for a club where big clubs have come before and taken players away. I understand that so therefore, I guess, he is a player they will be looking at.
"That's all I can say because he has been terrific for us."
Pardew added that he feels Sissoko has undoubtedly improved since his January 2013 move from Toulouse.
"He is only a young player, 25, and he has already got 27 national caps for France. This is a guy who could win 50, 60 or 70 caps for France," the boss added.
"He is a powerful player and he is better player now than he was back then.
"He has technically improved, without a doubt."
