"Can he expect a call? Yes," said Wales manager Coleman.
BEN TURNER FACT FILE
21 August 1988 in Birmingham
Coventry City, Peterborough United (loan), Oldham Athletic (loan), Cardiff City
Did you know?:
Turner won his England under-19 cap against Czech Republic in May 2007
Wales youth team coach Brian Flynn initially approached Turner two years ago but the Birmingham-born player did not provide proof of his Welsh heritage.
But Coleman and the Football Association of Wales now plan to contact the 6ft 4ins defender officially in an effort to finally confirm the player's Welsh qualification.
Turner, who is currently keeping Wales centre-back Darcy Blake out of his favoured position, has confirmed that two of his grandparents are Welsh.
He would add further depth to Wales' central defensive options as Blake and Swansea City's Ashley Williams are Wales' current first-choice defensive partnership, who helped Wales win four of their last five internationals.
Premier League trio James Collins, Danny Gabbidon and Danny Collins are also available to Coleman, while Lewin Nyatanga is further down the Wales pecking order.
Turner has insisted he will not commit to Wales before being asked officially by Coleman or the FAW.
"Ben is on the radar - and especially after Sunday," said Coleman, who worked with Turner when he was Coventry manager.
Speed would want us to win - Coleman
"I had him as a young kid at Coventry, he had problems with injury but he seems to be overcoming that and he is now progressing and turning into the centre-half I thought he would be.
"I was interested [to see] how he did against Luiz Suarez of Liverpool on Sunday who is a very tricky striker
"We know he can head the ball, has a good left foot, is strong, quick and domineering but I wanted to see how he would be like against that type of player as international football is pretty similar to that, where players play in pockets and not come at you one-on-one.
"And I thought Ben Turner was outstanding, he was one of the best players on the pitch."
Turner could win his first Wales call for their 27 May friendly against Mexico in New York, providing do not qualify for the Championship play-offs in May.
His next opportunity to play for Wales would be the friendly with Bosnia-Herzegovina at home on 15 August.
Coleman would ideally want to bed Turner into his Wales squad before their opening 2014 World Cup qualifying match
at home to Belgium
on 7 September.
