I doubt that Saga will come back to Aalborg. They wanted to keep him, but could not agree on the economical side.
He made a very slow start to his Aalborg career - along with all the other players that were crowned Danish champions in May. Caretaker manager Bruce Rioch never got going and the team had a 2-2-6 record in the league by early November and . Sagas efforts matched the team effort: he worked tirelessly but didn't find the net before a late September cup game against lower league opposition. Supporters recognised and applauded his effort but the lack of goals was not too popular with the fans...
Aalborg managed to claim a ridiculously easy spot in the Champions League playoff by brushing aside FK Modrica and FBK Kaunas. This earned them games against ManU, Celtic and Villareal. Suddenly Saga looked a much better player than in the Danish league games. In the 6-3 away defeat at Villareal Saga was by far Aalborgs MoM and the supporters were warming to him.
After the Villareal game Rioch was shipped off (the game was lost partly because of tired players and he made a grand total of zero substitutions!) and things took a turn for the better for Aalborg and Saga. Under caretaker manager Kuhn the team did not lose a single game - they got 7 wins and 5 draws!
In the league they claimed 4 wins and 3 draws, in the cup they won 2 games, and in the Champions League they got draws against ManU and Villareal and a victory over Celtic (giving them 3rd spot in the group and knocking Celtic out of european competitions this season). Saga got more goals in this period and by the end of his loan spell the supporters were quite keen on getting him signed. The DoF admitted as much but also said that it was not a likely move as the economical matters were a stumbling block.
And so back to Southampton he went, with 5 goals in 24 games. But counting from when the team got back on track it was 4 goals in 13 games. His confidence should be ok and his match fitness shouldn't be too bad either after playing a lot the last few months. Aalborg fans actually complained that they should have received money for getting Saga match fit, so all in all the loan move might prove to be a good move by SFC. If he starts banging them in regularly, I'd be quite happy ;-)
