By Greg Stobart | Northern Correspondent Wigan Athletic manager Roberto Martinez will leave the club in the summer,can reveal.The Spaniard and the club have mutually agreed not to negotiate a new contract at the end of the season and he will move on in the summer, regardless of whether the Latics stay in the Premier League.Martinez's current deal expires at the end of the season and, contrary to reports at the time, he did not sign a contract extension last summer, although he did agree improved terms after turning down Aston Villa.Martinez, 38, left Swansea to take the Wigan job in 2009 and is widely considered as one of the most promising managers in the country after steering the club to safety in the last two years.Wigan stayed up on the final day of last season and currently face another relegation battle as they sit second from bottom in the Premier League table with six games to play ahead of Wednesday night's home match against leaders Manchester United.Wigan owner Dave Whelan is believed to feel the time is ready for a change at the DW Stadium while Martinez himself wants a new challenge, although he has no job lined up.He is understood to regret turning down the opportunity to take over at Villa last summer after he had been given permission to hold talks with the Midlands club.At that time, Martinez said he felt a loyalty to Wigan, where he spent six years as a player, but he is now eyeing up potential summer vacancies as he looks for a new project.Martinez and Whelan have constantly spoken of their strong relationship but cracks have appeared in recent months, not least when the owner openly questioned his manager on a national radio station following last month’s defeat to Swansea.“That was our worst performance in four or five years,” Whelan said on BBC Radio 5 Live.“I will have a meeting with him on Monday morning and ask him some questions about the performance and his selection. We had three quality players on the bench and I want to know why.”
