MLS announced the arrival of Sergio Busquets with a picture of Alvaro Arbeloa

Major League Soccer announced the arrival of Sergio Busquets with a picture of Alvaro Arbeloa on social media in a huge gaffe.

Inter Miami, who unveiled Lionel Messi last night, confirmed the signing of former Barcelona captain Busquets on a two-year deal.

The 35-year-old will occupy a 'Designated Player' slot and is expected to join the Miami-based outfit in the coming days.

The move to America will see the World Cup winner reunited with his former Barca teammate Messi, who signed for David Beckham's team following his departure from Paris Saint-Germain.

It's another big coup for the MLS, who announced the transfer of the Spanish midfielder on Twitter.

But the league inexplicably used a picture of former Liverpool and Real Madrid defender Arbeloa.

MLS shared a picture of Arbeloa, accompanied with the caption: "All he does is win."

The post was swiftly deleted, with the league acknowledging their hilarious error. In another tweet, they wrote: "Why do Arbeloa and Busquets look so similar in these. admin needs new glasses..."

Busquets, meanwhile, joins Inter Miami having spent his entire professional career at Barca. He's excited about the new challenge ahead.

"This is a special and exciting opportunity that I'm very excited to take. I'm looking forward to this next step in my career with Inter Miami," he said.

"I was impressed by the club when I came with Barcelona last year and now I'm happy and ready to represent the club myself. I can't wait to help bring the success that this ambitious club strives for."

Inter Miami managing owner Jorge Mas added: "I am excited to welcome Sergio Busquets to Inter Miami. Since day one we have set out to bring the world's best players to Inter Miami. Sergio's repertoire speaks for itself."
