Borussia Dortmund are confident about keeping Ian Maatsen.
The fullback joined BVB on loan from Chelsea in January, without a permanent option.
However, the Blues have said Maatsen can be sold this summer.
Premier League clubs are interested in Maatsen, but his priority is to stay in Dortmund.
Indeed, his father Edward said last week: “We are working on him staying at the club.”
