Norwich City have emerged as shock promotion contenders this season, and under Daniel Farke, they look like they could certainly be the dark horses for the remainder of this years campaign. 

But all of their hard work could come crashing down, as it was reported by RP-Online that German giants, Bayer Leverkusen have Farke on their shortlist to succeed Heiko Herrlich who has endured a poor start to the season in Germany.

There is now a winter break in the Bundesliga and the German giants are looking at the possibility of replacing Herrlich who has his side struggling in 11th place in the table as we approach Christmas.

This latest development could come as a devastating blow to Norwich's promotion chance this season, as they are well in the hunt to win promotion back to the Premier League this season.

But if Farke was to depart for Bayer Leverkusen, then who could the Canaries potentially turn to as their new manager?

Find out here....

If Farke departed Carrow Road, then Jokanovic would surely be one of the leading candidates that Norwich would want to take charge of the team.

He guided Fulham to promotion to the Premier League last season, and Jokanovic would be confident of replicating that with a Norwich side that have already put themselves in an ideal position to win promotion.

Di Matteo has been out of work since an unsuccessful spell with Aston Villa and will be keen to step back into the managerial hot seat.

He has proved everyone wrong in the past, and famously lead Chelsea to their first Champions League title and would bring that winning mentality with him to Norwich as they battle to win promotion to the top flight.

Calleja has been out of work since he was dismissed as manager of Spanish side, Villarreal just ten days ago as his side were struggling near the bottom of the La Liga table.

He will be keen to prove himself in management after struggling with Villarreal and he could be tempted to join Norwich with the real possibility that they could win promotion to the Premier League this season.

At the age of 40, he is a relatively young manager like Farke was when he was appointed, and would be an interesting option to consider as he could potentially replicate the success Farke has had, providing he is given an adequate budget.
