Michael Laudrup believes Ki Sung-yueng will prove to be a shrewd acquisition for Swansea after making a promising debut against Barnsley.
The 23-year-old only received international clearance to make his midweek bow a few hours before a Capital One Cup clash with the Tykes, with a £6million switch from Celtic finally signed off.
He offered enough during a routine 3-1 win to suggest that he can be a big hit in South Wales, with his creative instincts and playmaking abilities making him an ideal fit in a footballing side.
Laudrup is, however, confident that there will be much more to come from Ki once he has settled into his new surroundings and adjusted his game to meet the demands of life in the Premier League.
The Swans boss said: "I thought he did quite well and it was obviously very difficult for him.
"He has only been here in training for a couple of days and we had to wait until 2.30pm so we could have the go-ahead that he could play.
"It was difficult as we had Jonathan de Guzman and Kemy Agustien in the midfield three with him, and those three players have never played together before.
"Once you get to know each other things will start to move more fluidly and he needs to be given more time.
"It is the same for Kyle Bartley, it is important for them to continue to train with the rest of the squad and once you know your team-mates more, things get better."
Asked if Ki could make his Premier League bow against Sunderland on Saturday, Laudrup added: "We will have to wait and see how he is tomorrow and what happens after that between now and the end of the week.
"There are three days left of the transfer window and in any minute something can happen so we will see on Friday after training what players we have and who is fit and available."
