Arsenal, Inter Milan and Tottenham are monitoring the progress of Borussia Monchengladbach defender Jaanik Vestergaard, ahead of a potential summer transfer.

TuttoMercatoWeb write that Inter are considering a loan move with an option to buy, or a straight purchase this summer. However, if they wait until the summer, the Italian outlet claim Arsenal and Spurs will challenge them.

The Gunners will lose Per Mertesacker┬áto retirement at the end of the season, and TMW claim they’re looking for a replacement with similar characteristics. Vestergaard, 25, probably fulfills that criterion.

Like Mertesacker, he’s a bit of a giant, at 6’6″. He also used to play for Werder Bremen. In fact, he’s played in Germany for his entire senior career. Right now, the Dane is a regular for Monchengladbach. The Bunsdesliga club have selected him 19 times this season.

The question is, whether Vestergaard is ready to make the step up to a club like Arsenal. With respect to his former and current employers, none of them provided the same level of competition or pressure.

For example, he still hasn’t played a single European match, Europa League or Champions League. Arsenal are already close to signing 20-year-old Konstantinos Mavropanos, so they need to focus on first-team additions now.

I’m not sure that’s what Vestergaard is.
