Norwich City manager Daniel Farke admits he's seeking a new left-back signing.
Manchester United defender Brandon Williams has been linked with the Canaries.
“I can only praise the club and the work of Stuart Webber. What he has done is fantastic so far," said the Canaries' head coach. “My gut feeling is each signing is spot on. That is not easy for a self-funded club.
"We can't spend £15m to £20m on one player. We know the final pieces will be decisive if we are there with a top transfer window or not. We definitely need to bring in a full back option. That is for sure.
“We should definitely do something in central defence and maybe holding midfielder. In order to be competitive we need to do a bit more. As a head coach of course I want players in as early as possible to work with them. If it was the difference between £1m or £2m then we would have brought targets in. Sometimes you have to be patient and wait.
“Maybe in these terms it is not the worst situation to start against Liverpool or Manchester City. Against such teams even a top class team might find it difficult.
“Our policy is never to comment on rumours or speculation until business is done. We definitely want a full back, especially one capable of playing left back, because we only have one in Dimitris Giannoulis and to be competitive on this level you need two options for every position.
“We also need a centre back and a central midfielder would be good. We will stay awake but we won't comment on names or rumours. That is not our style."
