Asamoah Gyan expressed his delight at joining "an important club" in Al-Ain but refused to be drawn on his long-term future.
Gyan completed a shock loan switch from Sunderland to the United Arab Emirates over the weekend and was unveiled at the Khalifa Bin Zayed Stadium on Monday morning.
The Ghana international was thought to be unsettled on Wearside for several months but his decision to swap one ofEurope's biggest leagues for the Persian Gulf emirate surprised many.
Gyan said: "I'm really happy to be here. Al-Ain is an important club and this is a big challenge for me. There will be a lot of expectations on me, but not pressure.
"Everybody who has seen me in the World Cup and at Sunderland knows what I am capable of, but this is a new challenge for me as I'm a new player here.
"We have quality players in the club to win games and do well in the championships. We will try to build a winning team."
When pushed on whether he intended to remain with Al-Ain when his season-long loan deal expires, he added: "I don't promise. I'm somebody who doesn't promise."
Cynics have suggested Gyan has quit the Barclays Premier League for the riches on offer in the Middle East with reports in England claiming the 25-year-old will quadruple his wages at his new club.
But the former Rennes striker insists he has gone for "the challenge".
He said: "It's a challenge to me. I made a decision with my family. Talking about the Asian league it is improving very well"
Gyan's arrival means Al-Ain have now signed the four permitted overseas players for the coming season - Argentina'sIgnacio Scocco, Mirel Radoi of Romania and Saudi Arabia's Yasser al-Qahtani were already on board.
Club director Awad Bin Hasoum Al Darmaki said: "I believe that a player of the calibre of Asamoah Gyan will add value for Al-Ain.
"He is ready to accept challenges anywhere in the world but success is not only the responsibility of a single player and coach, I believe it's an equation that each part has its role and responsibility."
