Tottenham are reportedly keen on signing the Real Madrid midfielder on loan.
The 25-year-old midfielder has been pushed further down the pecking order at Madrid due to the signing of Mateo Kovacic, and Tottenham are in the market for a new central player.
The likes of Eric Dier, Nabil Bentaleb and Ryan Mason have all been utilised in the double pivot role in a 4-2-3-1, but the lack of depth is a real worry. Mauricio Pochettino has been linked with making a move for a new midfielder this summer, and with just over a week left of the transfer window, he needs to move fast to complete another signing.
Illarramendi looks a great option, and with his future at the Bernabeu in doubt, Spurs are considering a loan deal to bring him to White Hart Lane for the season.
However, there is a complication in any potential deal, as Illarramendi wants to be playing Champions League football, something the Lilywhites cannot offer the former Spanish youth international.
