Club Olimpo
At the start of the 2011–12 season, Palomino appeared in the first four league matches of the season. However, he suffered injuries on two occasions that saw him sidelined for two months. Palomino did not return to the starting lineup until 5 November 2011, when his team drew 1–1 against Club Olimpo. After returning from injury, he continued to regain his first team place, rotating in playing the centre–back and left–back positions. Despite being sidelined on three more occasions later in the 2011–12 season, Palomino went on to make 25 appearances in all competitions.
