U.S. international defender Oguchi Onyewu is eyeing either a Premier League return or a switch to the Spanish league once his Standard Liege contract expires in June.
The American will have completed his fifth season in Belgium's Juliper league by the time his contract expires at the end of the season.
After renewing terms with the UEFA Cup participants twice during his stay, the 26-year-old has admitted that it is time to move on.

Onyewu had a spell at Newcastle United in 2007 and made 11 appearances for the side while on loan from Liege, and has once again attracted interest from the crisis-hit club, according to the paper.
However, Everton and Middlesbrough are also thought to be keen on the center back, particularly after watching his performances last month in the Champions League against Liverpool and on Thursday against the Toffees in the UEFA Cup.
"My contract will soon end and I do not intend to sign," he told the press. "I've already twice extended my contract and after five years it is time that I look elsewhere."
There is a possibility that Standard will let its star leave in January in order to ensure a fee is received in return for his services.
