Crystal Palace are rushing to complete the signing of goalkeeper Lucas Perri before they face Tottenham at the weekend.
They face Spurs in the FA Cup on Sunday in an exciting London derby.
And the 21-year-old goalkeeper Perri should have his medical completed and contract signed in time for him to be eligible for the game.
Palace rushed through a goalkeeper signing after both Wayne Hennessey and Vicente Guaita suffered significant injuries.
39-year-old Julian Speroni stood in against Liverpool at the weekend, but committed a crucial error in a 4-3 defeat.
If the Perri deal is done, he will start against Spurs.
