Manchester City boss Manuel Pellegrini admitted he may try to extend Frank Lampard's loan spell at the club.
The former England man made it three goals in two games with a man-of-the-match performance in City's 7-0 Capital One Cup victory over Sheffield Wednesday.
Lampard made the surprise move to join City on loan last month from sister club New York City having been released by Chelsea in the summer.
The deal is until the start of January but, with the Major League Soccer season not beginning until March, Lampard's form has led to speculation that Pellegrini will try to keep him for longer.
The Chilean said: "At the moment I think it's not the most important thing. We'll see what happens in January.
"We have two or three months more to decide but I will look at what is important for the club and for the player. We must talk about a lot of things but it's not impossible."
Pellegrini picked a very strong team as City began the defence of their title but the hosts were frustrated by a resolute Wednesday display in the first half.
However, once Lampard bundled home the opener two minutes after the break, the floodgates opened. Edin Džeko scored in the 53rd minute and Jesús Navas made it three just over a minute later.
On the hour mark Yaya Toure slotted away a penalty after Kamil Zayatte saw red for felling Lampard and Džeko added his second 13 minutes from time - his 11th in 11 League Cup games.
Teenage striker Jose Angel Pozo marked his debut with a goal in the 88th minute and Lampard slid in the seventh in injury time to set up a fourth-round meeting with Newcastle.
