Tang En did not dare take Villarreal CF lightly. In the past, though the team was only capable of ranking between the lower and middle tiers within Spanish football leagues and had little fame to their name, Tang En knew exactly how strong this season's Villarreal CF was.
The 05-06 season was one of the most glorious seasons for Spain's "Yellow Submarine," Villarreal CF. From the beginning of the Champions League qualifiers, where they defeated Everton (ranked fourth in the English Premier League), they commenced their stunning journey as the dark horse of the Champions League. On the way, they eliminated Celtic F.C. and A.S. Roma, battling all the way into the semi-finals of the Champions League. However, they could not defeat Wenger's Arsenal in the semi-finals and had to, regrettably, halt their steps at reaching the top four.
