Millwall manager Kenny Jackett insists talk of turning on-loan winger Jason Puncheon's move into a permanent deal is premature.
The 24-year-old, who has joined the Lions from Southampton until 3rd January, scored on his debut in a 1-0 win at Middlesbrough on Saturday.
However, Jackett claims the tricky winger has plenty left to prove before he can even consider making a move to sign him on a full-time basis.
"It is a great way to start your career at a new club and he is a player with a lot of ability," he told skysports.com.
"He has his Millwall career in front of him now and we will see how he responds from an impressive debut.
"It is a loan deal at the moment and that is all it is.
"He played very well on his debut, but that was only one game and it is only the early stages of his loan, so we will have to see how things progress with him first before considering turning it into something more permanent."
Millwall are short on numbers in attack following injuries to key players such as Chris Hackett, Theo Robinson, Kevin Lisbie, Neil Harris and Daniel Schofield, but Jackett is hoping to see three of those stricken stars fit for selection this weekend when the Lions travel to Preston.
He said: "We are hopeful of having the likes of Kevin Lisbie, Danny Schofield and Chris Hackett back for the weekend, but it is touch and go, so we will have to assess their situation closer to the time."
