Daniel Farke stopped short of saying ‘I told you so’ but warned Norwich City must keep grinding to seal promotion to the Premier League.

Farke’s pre-match prophecy about the threat posed by Swansea City was underlined by a hard-fought 1-0 league win on Friday that kept the Canaries two points clear of the Championship’s chasing pack.

Both Sheffield United and Leeds responded in kind and the City head coach is now braced for more of the same when Hull City visit Carrow Road on Wednesday.

“What happened against Swansea is a perfect lesson,” he said. “A good lesson for everyone that anything can happen. We hosted a mid-table side so we win very easily, no, you have to be prepared, switched on and that will be the same against a really good Hull side.

“Swansea were in the Premier League a few seasons ago with good players. Maybe they are missing a cutting edge but I knew before the game it would be complicated and the lads were prepared. You have to work on details every day.

“To pick up a clean sheet was crucial and our defending, for me, is also outstanding at the moment.”

Farke was less impressed with Swansea’s midfield dominance in the first half, but resisted the temptation to introduce the likes of Mario Vrancic or Moritz Leitner at the interval.

“I was tempted (to make changes) because if we were not able to influence things in the opening minutes of the second half I would have had to influence things pretty quickly with some changes,” he said. “The lads found a different level.

“We talked about many, many things at half time. Our feeling was the pressing was not on the same level as recent games. It was simply not good enough. Swansea had brilliant solutions so we had to change some details in our pressing and also in possession, our quality, and how we move the ball needed to improve. We changed our positioning and sometimes these small things have a great effect in football.

“It was important to be mentally strong and to keep our nerve. You cannot afford to become annoyed that it is not as easy as recent weeks or you are not scoring as many goals. You have to accept periods when the opponent is on the front foot.”
