Jordan Rushworth  Sibley is a player that has demonstrated a lot of ability with his performances for Derby, although he has not had quite as good a season as the Rams would have been hoping for after his impressive breakthrough towards the end of last term. There is plenty of potential in the attacking midfielder and if he is developed in the right way there is nothing to suggest he could not make it in the Premier League. Sibley has been challenged by Wayne Rooney at times and he has responded to those challenges so seems to be someone that needs to be driven. West Ham have been very good at identifying the right players to sign from the Championship in recent windows, so you would back the Hammers to get it right were they to make a move for Sibley. However, whether he could come straight into their side at this stage and make a major impact remains to be seen. He has not always been a regular starter for the Rams this term, so it might be another year or so before he can command regular Premier League starts. Jacob Potter I like the sound of this potential deal. I don't think we've quite seen the best of Sibley this season, and he hasn't been able to build on a number of impressive performances towards the end of last year's campaign. But when he's at his best, he can cause opposition defences a number of problems with his trickery on the ball. He's still got age on his side as well, and could be a shrewd signing for West Ham if they can stump up the cash for him in the summer. I think Sibley is capable of playing regularly in the Premier League in the future, and this would be an excellent signing by the Hammers.
