The former Porto youngster, who signed for the Blues last summer, was loaned out to Vitesse last season but having flashed ability both in the Eredivisie and at the World Cup, it was no surprise to see bigger clubs chasing his signature.
A host of Premier League teams wanted to take the Ghana international on loan, but it was the Toffees who landed Atsu – shortly after signing Chelsea striker Romelu Lukaku on a permanent deal after the Belgian impressed on loan at Goodison Park last season.
Some fans have now speculated that Atsu will end up staying on Merseyside long-term, but manager Roberto Martinez has played down talk of a permanent deal, simply saying the deal is for this year only.
"The loan market is what it is, it's the loan market," said Martinez. "We always want to use that to our advantage and here again is a really good opportunity for the three parties – the parent club, ourselves and the player."
"All we want is that Christian can develop fantastic and unforgettable memories at Goodison with our fans and we hope at the end of this 10-month period that he is a better player and that both clubs are happy with what has happened."
However, with Eden Hazard, Oscar, Willian, Andre Schurrle and Mohamed Salah all competing for roles in Chelsea's three attacking midfield spots, Atsu will find it hard to break into the Chelsea team in the coming years. Factor in that the Blues appear to rate Lucas Piazon and Thorgan Hazard more highly than Atsu, and it seems that his future lies away from Stamford Bridge – and Atsu hinted that he could stay at Goodison Park.
"I can't tell you the future but I don't know how long it will take for me to get back to Chelsea," said the 22-year-old. "Looking at the players Chelsea has, my playing time would not be much and for me I have to play football as a young player."
Given Lukaku's success under Martinez, it would be no surprise to see Atsu fare well too – and with a tough time ahead of him at Chelsea, he could follow the Belgian's lead in heading to Everton for good in search of first team football.
