OXFORD United have switched their attention to other targets after Jem Karacan turned down the chance to sign.

The 29-year-old is a free agent after being released by Bolton Wanderers earlier this summer.

United had been in discussions with the midfielder for more than a week, offering an improved offer before last weekend after their initial contract was turned down.

But U's head coach Karl Robinson confirmed this morning their hopes of signing Karacan were now over.

He said: "We move on.

"But I’ve got one or two players who I didn’t think we could get, that might be available now.

"I could have pushed, but no."

United have signed seven players this summer, but Robinson is still chasing another four.

He said: "We do need two midfield players, we do need a striker and we need another winger.

"We’re on the hunt for that and we’ll see what we can do."

Sam Smith, who is wanted by several clubs, is top of United's wish-list when it comes to strikers.

On Saturday, Reading manager Paul Clement suggested the 20-year-old would be made available for loan, but it was felt they would need to make a signing in his position first.

The wheels could now be put in motion for Smith to leave the Madejski Stadium, following Sam Baldock's transfer from Brighton & Hove Albion last night.
