Thats the entire point, we didnt turn to Heitinga to win the game, we turned to Felli and Osman, the fact Johhny scored was just a bonus
He thought Felli would be more efffective than Vellios and given his form this season I would tend to agree. We were lucky to still be in the game because for the majority of the match Bolton were the better side, but to say it was a lucky substition is the naive part in my eyes
Luck obviously plays a part in any game of football but he made a tactical change that worked. Jelavic wasnt getting a sniff so was completely ineffective. Osman playing in a more advanced role gave us the initiative and Felli was the man who kept the ball in play to tee Hietinga up so I would say it was a pretty effective change
