Tottenham Hotspur will reportedly only allow Dele Alli to join Paris Saint-Germain in the final stages of the January transfer window if the London club can secure a return for Christian Eriksen.
Alli has been strongly linked with a move to the French champions in recent weeks, and it is understood that the Ligue 1 giants are pushing to sign the England international on an initial loan deal.
However, according to The Mirror, Spurs chairman Daniel Levy will not sign off on a move unless his club can sign a replacement, with Giovani Lo Celso's recent injury meaning that Jose Mourinho's side are short of options when it comes to the number 10 position.
The report claims that Eriksen is the club's first-choice target, but Inter Milan boss Antonio Conte recently insisted that the Denmark international would not be leaving the club before the end of the month.
The playmaker has largely struggled to make his mark in Italy since arriving from Spurs last January, contributing just five goals and three assists in 42 appearances in all competitions.
Eriksen was a key player for Tottenham during his time at the club, though, scoring 69 goals and contributing 89 assists in 305 outings for the capital giants.
