MILLWALL chief executive Andy Ambler has admitted that new arrival Nathan Tyson could be signed permanently in the summer if he impresses whilst on loan.
Tyson has joined the Lions until the end of the season from Derby County and is expected to make his debut for the club against Burnley at The Den on Saturday.
The 30-year-old has 18 months left on his contract at Pride Park but could be handed an extended stay in South London if he proves a success.
Ambler told NewsAtDen: "The idea has been floated. That's in Nathan's hands really and down to if he impresses in the second half of the season.
"But it is something we have discussed and he may be available should we want to go down that route. It's down to him to do well and us to see what direction we are going in."
Ambler added: "Kenny had made contact with Nigel Clough a little while ago in the course of seeing who may be available and since then he's been weighing up several options.
"We made our move on Tuesday and I got involved in the finances at that stage. We were able to put a deal together to bring him to the club and it was as simple as that really."
Despite Tyson's arrival, Millwall are understood to be in the market for another frontman during the January transfer window, but Ambler played down that suggestion.
He said: "Kenny's always looking at opportunities to strengthen but we're now back to four strikers – with Dany N'Guessan doing well – so I don't think he would want any more."
