Grigg is answering all the questions being asked of him

Questions over Will Grigg's mentality and motivation have been firmly answered by the striker since arriving at Stadium MK, said Russell Martin.

The striker made just 12 appearances for parent club Sunderland this season, and hadn't scored in well over a year before firing home in the 4-3 win over Northampton last Saturday. He added another goal to his tally on Tuesday night in the defeat at Shrewsbury, and has turned provider for two goals prior to that too.

But Sunderland fans voted overwhelmingly in favour of cutting the striker loose at the end of the season, with only 4.2 per cent of voters believing he could still offer something at the Stadium of Light.

However, Martin said despite hearing detractors in his fact-finding mission to sign the striker in January, he has been delighted with how Grigg has impacted his side since arriving.

"He's not driven by money or accolades, he's driven by having respect of his team-mates," said the Dons boss. "We all know what a good player he is. He's had a tough time.

"One of the things he's been unfairly accused of by people who don't know him or aren't behind closed doors is losing a bit of hunger. When I spoke to people about him, people questioned that, and you don't want to have that questioned as a character. Other than his ability, which you cannot question, people might ask about his character but he has been brilliant.

"He;s become really important ot us really quickly. As long as he can prove us right and everyone else wrong, with his goals and in other ways, we'll really enjoy having him here."
