Barcelona vice-president Ferran Soriano cannot guarantee coach Frank Rijkaard will be with the club next season.
"We've decided not to talk about this until the end of the season because we are concentrated and very focused.
"The two matches against Manchester United are very important for them and for us. And we don't want to talk about anyone else."
He continued: "We've been with him for five years and he has been doing an extremely good job. It can be difficult to manage such a big team with such a number of stars.
"It's not easy to manage Ronaldinho, Messi, Henry and Eto'o and the like so we like the way he works, his personal style and the way he represents the club.
"Obviously the fact we are not getting the results in the domestic league is the fault of everybody including us and including him but we are very happy with Frank Rijkaard."
