Dalian finished 9th and got to the Semi finals of the Chinese FA Cup in his first half a season, which was above and beyond where they were expected to be.

In that infamous match against Barcelona, in which Rafa wanted to play Casemeiro and go more defensive, but was forced to field an imbalanced attacking side, which left them wide open, which Rafa was furious about as he felt he was stitched up, I believe they were unbeaten in the Champions league under him and achieved their biggest ever win domestically and in Europe.
