The Ghanaian winger was only signed by the Blues last summer from Porto, but he spent the 2013/14 campaign away from west London with Vitesse Arnhem.
At 22, Atsu is being tipped to have a future at Stamford Bridge, yet a second temporary switch looks likely.
This has alerted Villa, West Ham and Everton, who are all ready to offer him a Premier League chance.
The latter may have the best chance due to Europa League action and their relationship with Chelsea – from whom they loaned Romelu Lukaku last season.
West Ham are also in the battle as Sam Allardyce plans to introduce a more attractive brand of football to Upton Park, while Villa are keen with securing cheap addition key for the Midlanders.
Chelsea want Atsu to pick a side with whom he will play regularly with a view to recalling him in 12 months’ time.
As well as the English trio, the likes of PSV Eindhoven, Hamburg, Celtic and Espanyol are looking at the wide-man.
