Could Hulk be on the way out?
There is no other way around it. Porto has been the biggest disappointment for a variety of reasons, followed closely by Borussia Dortmund. Both teams are in the same spot in their respective groups (3rd in the group with 2 matches remaining) and both weren't exactly drawn in the "Group of Death."
A lot was expected of Dortmund and rightfully so—they dominated the Bundesliga last season. But more was expected of Porto.
They had an unbelievable season last year, winning the league, the Portuguese Cup and the Europa League. The natural progression made it seem that they should have progressed to the Round of 16 with relative ease, something that seems in major jeopardy right now.
The departures of Andre Villas Boas and Radamel Falcao were supposed to be difficult to overcome, but not impossible. Besides those two departures, the team has remained the same, but the results have not.
Porto lost a coach that brought together the team for the duration of a whole year. The club won the league championship last year without losing a single game (27 wins and 3 draws, with a 21-point margin to runners-up and arch rivals, Benfica). Simply incredible.
Replacing Radamel Falcao has proven to be way more difficult than any Porto supporter could have envisioned. Falcao was one of Europe's most prolific strikers last season, which is not easy to replace. F.C. Porto is finding that out this season the hard way.
With two games remaining in the group stage, Porto is still within striking distance but far from where the team, its supporters and the media expected them to be.
Anything other than a progress through Round of 16 will be viewed as a massive failure. No one can deny that, especially considering the difficulty of the group or lack there of.
