Roberto Martinez - Wigan more mature after Bolton loss

Wigan manager Roberto Martinez says last weekend's 3-1 defeat at home to Bolton , which left the Latics 19th in the Premier League, has had a positive effect on his side as they prepare for Saturday's trip to Newcastle.

Martinez describes the defeat as "self-inflicted", a result of being too anxious to get positive results.

However, he insists his players have "grown massively" following the loss and head to St James' Park in good spirits.
