Ricardo Carvalho's arrival from Chelsea on Thursday may not be Real Madrid's last bit of business this summer, according to general manager Jorge Valdano.
Carvalho completed a £6.7million move to the Bernabeu after passing a medical in the Spanish capital and becomes the club's fifth summer signing, joining Sami Khedira, Pedro Leon, Angel di Maria and Sergio Canales.
Real, who finished second in La Liga under former manager Manuel Pellegrini last season, have been linked with a move for Germany star Mesut Ozil while squad players like Lassana Diarra could move on thanks to this summer's influx of players.
And Valdano admitted that the signing of Carvalho does not signal the end of changes to Jose Mourinho's squad.
"We are comfortable with the team that we have, but the exits and arrivals might not be over,'' Valdano said.
Valdano revealed that Mourinho is looking for add an attacking player to his squad before the transfer window shuts and while Ozil fits the bill perfectly, the Real general manager refused to confirm whether the Werder Bremen man was on Mourinho's radar.
"There could be new signings and the club are open to all different possibilities but I can't name more possibilities in regards to who."
