David Wagner has arrived in the UK as he prepares to become Norwich City's next head coach. 

The German-American is understood to have travelled to the country to finalise his appointment as Dean Smith's successor at Carrow Road. 

Norwich are awaiting documentation surrounding his work permit following changes to the regulations after the United Kingdom's departure from the European Union. There are also some legal aspects that need to be finalised. 

Those aspects make confirmation of Wagner's move to Norwich unlikely to be announced on Thursday - with the plan still for the 51-year-old to take charge of Sunday's FA Cup third round clash against Blackburn Rovers. 

An agreement for Wagner to take the job has been finalised, with the club now waiting for confirmation from the relevant authorities before they can publicly announce his arrival at Carrow Road. 

The ex-Huddersfield and Schalke boss will sign a 12-month rolling contract at the club and will be joined by long-term assistant boss Christoph Buhler at the club. 

Norwich parted company with Smith on December 27, with the initial shortlist including four candidates, which has been headed up by Wagner since the vacancy became available. 

His style of play, track record in terms of developing young talents and ability to create a connection with supporters were the primary reason that Norwich accelerated talks with Wagner. 

He also has a promotion from the Championship on his CV as well as a previous relationship with sporting director Stuart Webber from their time in Yorkshire together.

Wagner is likely to be unveiled formally at a press conference once his appointment is confirmed, although that may not happen prior to Sunday's clash against Blackburn. 

Following that fixture, Wagner will be given a full week to work with his squad ahead of his first Championship fixture in charge of the club away to Preston next weekend. 

Allan Russell and Steve Weaver have overseen the last two games with Norwich drawing 1-1 with Reading last Friday and 1-0 defeat to Watford on Monday. 

Both are set for a return to their roles as set-piece coach and head of football development respectively.
