Chelsea have upped their price for Conor Gallagher this month.
The Mirror says Chelsea were willing to sell the midfielder for £50m last summer.
However, they are now demanding £60m to part with Gallagher.
Tottenham are interested in the England international, though not at Chelsea's valuation.
Chelsea will come to the table for £50m, but are insisting he won't leave for less than £60m.
