Do Chelsea stick or twist? Do they go with what they have on the books, or do they trade in one Belgian forward for his international companion? Or will they reunite the two youngsters at club level? Chelsea are apparently among the clubs circling Christian Benteke after he requested a transfer from Aston Villa, but why would they want Benteke when Romelu Lukaku is returning from his loan period at West Bromwich Albion? If it comes down to a straight choice between them who should Chelsea opt for? We profile both men in the latest of our transfer battle series.

Place of birth: Kinshasa, Zaire
Current club: Aston Villa
Former clubs: Genk, Standard Liege, Kortrijk, Mechelen
Benteke arrived at Aston Villa from Genk for around £7 million last August, but clearly does not fancy another season trying to avoid relegation with Paul Lambert's side. Before moving to England, enjoyed a fabulous record of averaging better than a goal every other game in Belgium over three seasons.
What would he would bring to Chelsea? With Edinson Cavani apparently edging towards a move to Paris Saint-Germain, a move for Benteke appears to make sense.
Scored 19 goals for Villa last season to prove his value at the elite level in England. Would certainly fit the bill as the target man Jose Mourinho is keen to land with some reports claiming Fernando Torres and Demba Ba will be sold during this transfer window.
What they say about him: "You look at some of his performances and he's been unplayable at certain times. It's about doing it next year and then the next year and then the next year and then you can say he's arrived. But he's only a young boy who's learning his trade. He's only 22 years old. I think if you asked him he would tell you he's got so much to learn. Once he does it year after year after year then we can turn around and say we have a proper player." Aston Villa manager Paul Lambert.

Lukaku has been promised a chance to prove himself at Chelsea. Not that he needs to prove much about his prowess after rising to prominence in European football at the age of 20.
Lukaku finished the 2009/10 season as the Belgian league's top scorer with 15 goals from 33 outings despite spending much of the time as a substitute. Became the third youngest goalscorer in European club tournaments when he scored in the Europa League against Ajax at the age of 16. Chelsea paid £20 million for him from Anderlecht two years ago, but he needs time on the pitch under Mourinho.
What would he bring to Chelsea? A figure of real power and pace, Lukaku is tall and powerful. Has great awareness in his position, and is not afraid to finish. The question is: will he be allowed to develop at Chelsea? Scored 17 goals last season so is an obvious choice for Jose Mourinho to turn to.
What they say about him? "Romelu is probably one of the biggest talents in Europe at the moment. We are very lucky with him, being a very young striker, and Christian Benteke (Aston Villa's Belgium frontman, who was also nominated for the PFA Young Player of the Year award). We have two unbelievable talents coming through. I am looking forward to playing against him. He will be a world beater in England very soon." Vincent Kompany, Manchester City and Belgium captain.
