Jonathan "Joni" Montiel Caballero (born 3 September 1998) is a Spanish professional footballer who plays as a midfielder for Rayo Vallecano.
He made his senior debut on 25 October 2015, starting with the reserves in a 1–1 Tercera División home draw against Fútbol Alcobendas Sport.
[3] Montiel was first included in a first team matchday squad at the age of 17, remaining an unused substitute in Rayo Vallecano's 3–1 loss at neighbours Getafe CF in the last 32 second leg of that season's Copa del Rey, advancing on the away goals rule.
On 30 January 2018, Montiel signed a new three-year contract with Rayo and was immediately loaned to CD Toledo in Segunda División B.
[10] On 2 September 2020, after staying more than 20 days without training due to rejecting Rayo's renewal offer,[11] Montiel extended his contract with the club until 2024.
