Tottenham have made a loan bid for Chelsea defender Toni Rudiger.
He has not been a part of Lampard's squad for the last three Chelsea matches and could now leave before the October 5 deadline.
Tottenham have emerged as surprise candidates to take him on loan but Chelsea would prefer a permanent deal.
The 27-year-old has just two years remaining on his current contract meaning the Blues would expect him to sign an extension before leaving on loan.
According to Italian transfer expert Nicolo Schira, Spurs have now made their move.
He tweeted: "#Tottenham have made an official bid to #Chelsea for Toni #Rudiger on loan with option to buy. Talks ongoing. #transfers #THFC #CFC."
