In the first leg of the Porto vs Arsenal match, Arsenal did master the ball but that did not mean dominating the game. If you keep the ball in your area, back and forth from right to left, back to the goalkeeper, you control the ball. However, no shot to the goal is a silly thing done by Arsenal. Arsenal need to improve the front lines to be more effective in attack, this must be immediately improved if they want to win the match in the second leg and qualify for the next round.
In this fight when viewed from the game this result is fair enough for Porto who came with plans and got three points at home. Arsenal did not guarantee a draw let alone victory, because Arsenal played a very negative game. There is no ambition, there is no substitute for managers, only one change of players. Porto knows they have to try harder to bring something to London to play and I still think Arsenal will turn things around at the Emirates Stadium.
I missed out on the game but this was a crucial game, though I settled for highlights, Arsenal dominated the game fulltime but got unlucky when it comes to goals scoring. Porto winning Arsenal in the first leg sends a message to the English team to become prepared to hosts Porto in the second leg. Mikel Arteta and his team had a dissapointing results but they have nothing to worry about because there's full hope in the second leg of the round of 16. Gunners will bring on every they got left, this is certainly not an opportunity for them to misused rather make proper advantage of this particular chance.
