Borussia Monchengladbach chief Max Eberl is battling to keep hold of Jannik Vestergaard.

The Denmark international is attracting interest from Arsenal and Tottenham this month.

"We do not intend to let anyone leave this winter," said Gladbach sports director Eberl.

Vestergaard has been impressive at centre-half this season for Gladbach, who is tied to the Germans until 2021.

Arsenal and Spurs, along with Inter Milan, are pushing Gladbach to discuss terms, but Eberl is reluctant.
