The 31-year old striker joined Barcelona on a season-long loan.
The Dutch striker joined Blaugrana on loan after spending two seasons with Sevilla.
He was expected to train on Monday with the Barcelona squad and might be available for next week’s Champions League game against Bayern Munich.
Summer signing Sergio Aguero is currently on the sidelines and Barcelona desperately needed a striker to lead the line.
“It’s incredible being a Barça player and it’s amazing to be here” he said. “I look forward to doing a lot of big things for this team and I can’t wait to get started.”
“There are lots of different forwards here, but I’m tall and I’m good with my head. I know I won’t play all the time, but I have a good relationship with Koeman from playing for Holland, and he’ll know when he needs a player like me who’s good in the air.”
“Frenkie and Memphis are great people and I also know Ter Stegen from Borussia Mönchengladbach so I don’t think it will be hard to settle in.”
