Chelsea have registered an interest in Borussia Monchengladbach midfielder Manu Kone, 90min understands.

There are plenty of suitors for Rice, however, and so Chelsea are exploring all their options. 90min reported in January that Southampton's Romeo Lavia was once again of interest to the London side, who failed with a bid to sign the Belgian last summer.
