Barcelona have unveiled their newest summer signing, Sergino Dest.The 19-year-old right-back's £23.8m move to the Blaugrana from Ajax was officially confirmed yesterday, with his club presentation at the Camp Nou going ahead today.As many will know, every Barcelona arrival has to go through the arduous task of performing a skill routine at the club's home ground in front of the cameras.Down the years, many new signings have failed to deliver the goods and have been made to look rather foolish.So how did Dest do? Well, the American teenager's efforts were rather mixed. The former Ajax man showed off some silky skills, but there's also one clip of the American failing to have any control over the ball whatsoever.

Dest's struggles

Social media can be a cruel mistress at times.

Thankfully for Dest, another clip of him smashing part of his routine has also surfaced and it's pretty darn impressive.

Shades of Ronaldinho there from the talented full-back.

Dest can also revel in the fact that his presentation was nowhere near as bad as a collection of Barcelona and Real Madrid players.

Below, you can watch Ousmane Dembele, Paulinho, Marco Asensio and Theo Hernandez fail pretty spectacularly at the task handed to them at their respective unveilings.

Hernandez's hilariously bad effort at the Bernabeu will never not be funny.

But wait, there's more. Martin Braithwaite's unveiling at the Camp Nou earlier in the year saw the Dane try and fail to execute a rainbow flick, much to the delight of rival fans.

Braithwaite gets it all wrong

One day, Barcelona and Real Madrid will make wholesale changes to their player presentations, but for now, the pressure is on!
