City boss Lee Johnson said: "We'd like to welcome Rodri and his family to Bristol City. We want to play with two strikers as much as possible and therefore we need four strikers as an option.

"He's proved himself in Spanish football and we are looking forward to working with him. While this is an initial short-term arrangement, we hope it works out for him and ourselves in the long term."

Rodri will join up with his team-mates in time for Saturday's Sky Bet Championship trip to Luton.
