GILLINGHAM have made their first two signings of the summer with the free transfer captures of Gary Mulligan and Guylain Ndumbu-Nsungu.

Mulligan, an Irish under 21 international, impressed during his loan spell at the club this season and has joined on a two-year deal from Sheffield United.

The 21-year-old scored one goal in 13 appearances for Ronnie Jepson's side since his arrival in the January transfer window.

Ndumbu-Nsungu, a 23-year-old former Congolese under-21 international, has also signed for two-years after being released by Championship side Cardiff City.
