Barcelona will send scouts to the Netherlands on Friday to watch Ajax defender Matthijs De Ligt.

The 18-year-old has been included in Ronald Koeman's squad to face England and Portugal.

The Blaugrana view De Ligt as a long-term replacement for Thomas Vermaelan.

But the Catalan giants aren't the only club interested in talented centre-back. Manchester City, Manchester United and Arsenal have also been keeping tabs on his progress.

De Ligt made his Holland debut as a 17-year-old last year.
