Klopp clearly and repeatedly sends the message his priority is training the team to improve individually and collectively, and will not go for transfers until he thinks he got all he could from the players he has and this January will not be enough time to come to conclusions according to him.
he not only needs to know his players more but also fully experiences the PL and how different teams play, I remember Houllier only bought Hyypia and Henchoz after his second summer, they were average players they were specifically selected to counter the long balls and they worked.
