Ipswich Town are set to complete a loan move for the Welsh international.
According to reports today from South London Press Mick McCarthy's men have won the race for the talented twenty-year-old.
The Welshman has played four times for his country and was the second youngest player to represents Wales Under-21s having just turned 17. Williams' early development was hampered by a serious league break while playing for the Under-21s in 2011.
Since then, Williams's went onto play a pivotal role in the first half of Crystal Palace's promotion season and picked up the Eagles' young player of the year award. But Palace's January move for Tom Ince has seen the talented Williams move down further down the pecking order at Selhurst Park.
Crystal Palace boss Tony Pulis was keen to let the highly rated youngster go out on loan to gain some vital first team experience, which will aid his development. He told the Daily Mirror:
"We rate Jonny and we want him around long term. But he needs a regular run of games to get that sharpness back.
"I'd like to get him a good club and preferably a manager I know."
Mick McCarthy's steady hands have earned the Tractor Boys a very talented midfielder who will add much need flair to their squad. Ipswich Town are currently without top goalscorer David McGoldrick, with an injury that looks to keep him out for the majority of the season.
Wales Manager, Chris Coleman, has praised the highly rated Williams:
"He has a good future Jonny Williams and he has been exciting this camp.
"He is a pleasure to have because he is so enthusiastic and he is enjoying it so much and that just rubs off on everybody," he explained to the BBC Sport.
Jonny Williams is quite a coup for Ipswich as Charlton Athletic and Bolton Wanderers were both said to be interested in taking the starlet on loan for the rest of the season.
