The father of Celtic target Max Diskerud has revealed that his son has narrowed his potential destination down to just four teams.
Celtic are widely expected to sign another central midfielder in January, with Beram Kayal almost certainly heading back to his native Israel with Maccabi Haifa.
Everton's Francisco Junior is currently on trial at Celtic Park, whilst manager Ronny Deila also has an interest in Genk's Kara Mbodj, but he may cost up to £5m.
Another potential target for Deila is Rosenborg midfielder Mix Diskerud, who was in the United States squad for this summer's World Cup, thought he didn't get on the pitch for Jurgen Klinsmann's men in Brazil.
Deila will be familiar with the 24-year-old having played for Stabaek whilst Deila was managing rivals Stromsgodset in Norway, and reportedly wants to bring him to Glasgow.
Their hopes have increased this week after Diskerud's contract with Rosenborg expired, making him a free agent, and his father Paal revealed the midfielder has narrowed his decision down to just four clubs, with Mexican side Tijuana seemingly out of contention.
"Mix has recently concluded that four clubs have emerged as most appropriate for him, for different reasons," said Diskerud, with MLS.com reporting that the player would only move to North America in order to play for an MLS team rather than one in Mexico.
One of the clubs involved in the decision figures to be Rosenborg, with Paal Diskerud admitting that whilst there is no deal yet, an agreement could yet be reached.
"The parties are something apart," he told NRK. "But not anymore than that I think that possibly quite smoothly may be able to come to an agreement."
Celtic will surely be hoping that they are one of the four teams being considered by Diskerud, but it seems that this particular transfer saga has some time to run yet.
