Why it's a huge month at Leeds United for these three players for very differing reasons.
Leeds United sit in 17th place in the Championship and have a big month ahead - which does not look easy.
It starts in the worst possible way against promotion chasers Hull City, and ends (like last year) with a match against in form Derby County.
Head coach Steve Evans has put the onus on his players to show improvement, and there are three players in particular for who the month of December is especially important.
When Leeds United spend £3 million on a player, expectations are sky high. After splashing out their biggest fee on a decade to sign Chris Wood in the summer, the return has been a mixed bag.
Wood is Leeds United's top scorer with six goals, but there is real room for improvement, managing to land just one fifth of his shots on target.

When Leeds are playing well and Wood is scoring all is well, but he has been too reliant on service, and there are too many games where he is entirely ineffective, especially at home.
He has scored just once in the club's last six games and a barren December will leave fans further wondering if the club invested their money wisely.
Speaking of strikers, Lee Erwin is yet to score a competitive goal for the first team. That's not a fair reflection on his ability, it is more a product of the face he has played only 15 minutes of Championship football since signing.
Former boss Uwe Rosler did not consider him ready for the first team, sending him on loan to Bury, but he is back involved now and has a chance to make an impact.
This month is a big one for his chances across the rest of the season. If he struggles and so do Leeds, then there is a strong possibility they will sign a striker either permanently or on loan in the January transfer window - and this will affect Erwin's chances going forward.
Erwin needs to show he can be a first team player who can make a difference now, but he also must be given the game time to do so.
It's no exaggeration to say this next month could decide Sam Byram's career at Leeds United.
With his contract expiring in June, his future is racked with the uncertainty of not knowing whether he is a first choice pick for Leeds United's first XI.
If he plays well and holds down a place, then there will be added determination on the part of both club and player to thrash out a contract extension and commit his future to the club.
Should he continue as just a fill in when either Charlie Taylor or Gaetano Berardi are unavailable at full-back, and revert the bench when they are fully fit, an amicable parting of the ways could take place in the transfer window.
It will be Leeds United's only chance to cash in before losing him on a free transfer, a financial gamble they may not be prepared to take for a back-up player.
