Swansea City boss Brendan Rodgers hopes to keep hold of Tottenham defender Steven Caulker.
Tottenham have until the end of January to recall the 19-year-old, and have requested that Swansea err on the side of caution in the unlikely event that they should need to take him back to White Hart Lane early.
Rodgers said: "If we get through and he is still here then he will be able to play for us in the FA Cup.
"I have spoken to (Tottenham assistant manager) Kevin Bond and (coach) Tim Sherwood at length.
"They know we don't want to lose him but you have to look after your own club, and though they have centre-halves available you never know.
"Just like in our situation here, we have players that want to go out and play games, but I have to look after Swansea and Harry (Redknapp) and his staff have to look after Tottenham.""We have to respect he is a Tottenham player, as much as we may not agree and want him to play, he is their player.
