Grigg has scored 19 goals for the Dons during his loan spell in Milton Keynes this season and Karl Robinson is keen to keep hold of the 23-year-old.
He told the Milton Keynes Citizen: “We’ll try our best to get Will Grigg to play for MK Dons next season, but we’re realistic.
“We’ll certainly ask the question. Brentford paid a lot of money, and it’s a big investment. I’m not sure we can match the money they spent, but that’s just where we are.
“If the price is right, we’ll do the deal. Unfortunately, it has to be right for us for that to happen.”
