Chelsea keeping tabs on Borussia Monchengladbach's Denis Zakaria?

Borussia Monchengladbach midfielder Denis Zakaria has reportedly emerged as a transfer target for Chelsea.

While Frank Lampard has seemingly been prioritising bids for attack-minded players, it has become increasingly apparent that the Blues require additions in their defensive and middle thirds.

According to Bild reporter Christian Falk, Chelsea are one of a number of Premier League clubs who are continuing to monitor the development of Zakaria.

The 23-year-old, who would add some much-needed height to Lampard's squad, has just helped Monchengladbach earn a return to the Champions League.

Speaking to the Byline Podcast, Falk said: "It's true but Chelsea are not the only club keen.

"We know these clubs have shortlists and Zakaria is on the shortlist of Chelsea because he is a really good player, but he is also on the shortlist of [Manchester] United and the shortlist of [Manchester] City."

Falk added that it may take an offer in the region of £50m to tempt the Bundesliga side into selling the Switzerland international.
