Arsenal go into Thursday's second leg as heavy favourites following their performance in the first leg, but Goncharenko urged his side to look at match Roma's heroics and expressed his belief that Arsenal's open approach could allow the Russians a route back into the game.
"Roma played a magnificent match and made a miracle. We don't have a lot of chances to repeat the same miracle, but sometimes miracles happen in football," he explained pre-match. "Of course Arsenal are extremely motivated because winning the Europa League is the way into the Champions League, so this is their motivation.
"Arsenal have a philosophy and have stuck to it for a long time, for many years, regardless of their record.
"If they are losing or winning they still play to make supporters and fans happy. When you act like this, trying to cheer up the supporters, you can have some problems in the defence.
"Tomorrow's strategy for Arsenal could be done in different ways, but they will be focusing on their attack of course.
"If we play without believing in yourself and without faith it is better not to play at all. We need to go to the pitch believing in ourselves and that we can make it into the next round.
"We need to change some things, but it is not guaranteed that we will succeed or fail, so will implement some alterations then see how it happens."
