Former Bundesliga great Olaf Thon has stated that Barcelona are currently "average" and that Borussia Dortmund are clear favourites to overcome the Blaugrana in the upcoming Champions League clash at Signal Iduna Park on Tuesday night.
Both sides have suffered early hiccups in their respective domestic league campaigns, with Barca sitting fifth after only two La Liga wins from four, while Dortmund fell to a shock 3-1 loss to relegation candidates Union Berlin before the recent international break.
BVB recovered well though, hammering Bayer Leverkusen 4-0 in their most recent outing, while Barca strode to a 5-2 win over Valencia at the weekend.
