The 22-year-old has been in talks with Chelsea for weeks and is understood to have agreed personal terms with the West London club.
Chelsea are yet to make an official offer to RB Leipzig, however, with the move depending on the sale of Christopher Nkunku.
According to The Telegraph, Tottenham could swoop in and make a move having discussed the conditions over a bid with the German club.
Spurs are desperate to add a new number ten this summer having already missed out on Morgan Gibbs-White and Eze.
It’s understood that Simons would still prefer a move to Stamford Bridge but Spurs are still hoping to take advantage of their delay.
