Mtiliga announced his retirement from football on 28 August 2017,[15] and played his final professional match on 10 December in a 3–2, coming off as a 90th-minute substitute for Andreas Skovgaard in a 3–2 home win over Hobro IK.

In his time at Feyenoord, Mtiliga was touted as a coming Danish international by manager Ruud Gullit .

Although his inclusion came as a surprise to some,[22] Olsen found that Mtiliga's move to Malaga had improved his competitive level.
