Garry Monk's side will be looking to strengthen in the summer, whatever league they find themselves in.
Leeds United's Chris Wood celebrates scoring their first goal
With a quarter of the season to go, it would be fair to say that Leeds United boss Garry Monk has established what his best team is, and what his side's weaknesses are.
Given how Leeds have been flying this season, it would also be fair to say that they don't have many weaknesses, so surely Monk's plan for the summer will be to weed out the deadwood while looking to bolster an already strong side.
With that in mind, here's one possible signing that would make Monk's Leeds side significantly stronger, and one player that the Whites can afford to let go.
One to buy - Britt Assombalonga
Seeing as Leeds only have Chris Wood, Marcus Antonsson and Souleymene Doukara as their main striking options, it would make a lot of sense for Monk to sign another striker of serious quality for both depth, and to take some of the load away from Wood. Given the complete disarray at Nottingham Forest off the field, Leeds could do a lot worse than try and sign Assombalonga, who is lethal in front of goal. While Assombalonga doesn't run much and can be perceived as lazy, he times his runs superbly and with solid service, would resemble a mighty fine addition.

One to sell - Stuart Dallas
The 25-year-old winger has served Leeds well, but as this season's shown by his average at best form, when you start looking to compete at the higher end of the table/push for promotion, players like Dallas become expendable. While the Northern Ireland international still has age in his favour, realistically he isn't going to be first choice winger- on either flank - at Leeds next season, irrespective of what division United find themselves in. With that in mind, it might be wise for Monk to nudge him towards the door and get something for him, before his contract runs out in 2018.
