Robbie Fowler will rejoin his old friend - and MK Dons manager - Karl Robinson at the club.
While assistant manager at stadium:mk, Robinson then invited the 35 year old to the club in April to meet the squad and work with the Dons' strikers.
Fowler has now agreed to return on a more permanent basis when he has finished his current playing stint with Australian side Perth Glory, for whom he netted a hat-trick in last week's 3-1 win over Melbourne Victory.
Welcoming the new arrangement, Robinson said: "When his season finishes he'll be over on a regular basis working with the forwards as part of my coaching team."
Fowler's friend Dietmar Hamann is already a player-coach at stadium:mk.
