Journalist Germán Balcarce has reported that negotiations are well underway between Talleres and River Plate for the Colombian midfielder to join the Millonario team. His outstanding performance at Talleres has drawn the attention of the prestigious Argentine club. Portilla, who became a part of Talleres in early 2024, has established himself as a crucial player for the team, securing a position in the Colombian national team. Throughout his tenure at Talleres, he participated in 66 matches, netted one goal, and contributed five assists, demonstrating his defensive skills with the highest rate of recoveries and interceptions in recent months. River Plate is contemplating including him in their lineup for the latter half of the Argentine football season, depending on the availability of foreign player slots. Currently, only one slot is open, which might necessitate some players' departure to make room for both Portilla and fellow Colombian Juan Fernando Quintero, who is also nearing a transfer.
