Made a lot of sense considering the "system" he plays. He is not a CF.
Having said that, the "system" is the problem not Pelkas. Something has to give when you play with 3 centre backs.
Pelkas is an attacking mid that should be part of a 3 man midfield in a 4-3-3 or 4-2-1-3 if you like.
Understandable performance given the number of changes and new players. However, under this system we are effectively playing a midfielder short. Not a fan.
I too loved Matos for what he gave to the team, however Ferreira has the right to select his own players. There are no excuses that way, he will succeed or fail depending on his own decisions and be judged accordingly.
