Chelsea face competition for top defensive transfer target Josko Gvardiol.
The RB Leipzig defender attracted an offer from Chelsea last summer and remains on their radar.
Football Insider says Tottenham are following Gvardiol closely and are ready to challenge Chelsea for his signature.
His new contract, signed in September, contains a buyout clause of €50m. However, it is unclear when it will come into force.
The 20-year-old is tied to Leipzig until the summer of 2027.
