Borussia Monchengladbach are looking for a “mega offer” for Danish defender Jannik Vestergaard, according to reports.

Vestergaard has been attracting interest from Arsenal and Tottenham with his performances this season.

However, according to the German Express, only a huge transfer fee will convince Gladbach to part with their Danish defender.

The report says that while Spurs would be interested in a move in January, Arsenal would be willing to wait until the summer.

That could be because Gladbach’s general manager Max Eberl said: “We do not want to sell in January.”

Vestergaard joined Gladbach from Werder Bremen in 2016 and has gone from strength to strength.

He was ever-present for them during the first half of the Bundesliga season, and found himself in the Opta team of 2017 as one of the best performing defenders of the year.

The Dane is nearly two metres tall, and would certainly add plenty of height to Arsenal’s backline.

He is, though, contracted to Gladbach until 2021, so is unlikely to be sold cheaply.

Arsenal need to strengthen their defence as Per Mertesacker is retiring in the summer and Laurent Kosceilny cannot play every game without pain.
