Leeds announced that they had their transfer embargo lifted on Tuesday, meaning the Whites can now start to prepare for next season, and line up targets in the transfer window.
After a 15th place finish in the Championship, fans will be expecting an improvement next season - but reinforcements are needed at Elland Road if they are to push towards the play-offs.
Adding another striker will be a priority for Leeds having seen Mirco Antenucci, Billy Sharp, Souleymane Doukara and Steve Morison all have a go up front this season, but none of them really cemented their place in the starting XI, with Leeds clearly needing more quality in the final third.
Now, The Sun believe that Leeds are interested in signing Motherwell forward Erwin, with scouts travelling north of the border last week to watch the 21-year-old in action against Kilmarnock - a game in which Erwin scored in a 3-1 victory.
The 6ft 2in striker has now hit four goals in his last six games for Motherwell, attracting interest from Celtic and Sheffield Wednesday as well as Leeds.
Competing with Scotland's biggest club for the signature of one of the nation's top emerging talents would be bold from Leeds, but with the transfer ban now lifted, president Massimo Cellino may want to splash some cash this summer.
Erwin may be one for the future, but his recent form for Motherwell is clearly turning heads - and could now spark a three-team battle, with Celtic, Leeds and Sheffield Wednesday all involved.
