Arsenal is hosting PSG at home that seems to be the major reason why many people believe that they are in a better position to defeat PSG in the first leg they will be played in England, aside the defeat that Arsenal defeated PSG in the champions League this year if you look at the past records between Arsenal and PSG you will see that In their previous 5 meeting Arsenal has defeated them 3 times while there has been 2 draws. Football is unpredictable and there are chances that what we witnessed in the second leg match between Dortmund vs Barcelona and Aston Villa vs PSG is also possible but looking at the current form of Arsenal I don't think they will make any mistakes if they are able to get a good 2 goals leg against PSG in the first leg.
Enrique before the match with PSG says that Arsenal is one of the best teams in Europe, and he also understands that he will have to play the first match in London, it is a very important and difficult match and he would like to understand the goal of PSG, will they hold on to a draw or will they want to bring home a victory. This will be a difficult match for the PSG defense, and special attention should be paid to not allowing Arsenal to play close to the goal, so that they do not receive such free kicks as they did in the match with Real.
Most times club managers shower praises on the opposition team they want to play before the game to make them feel very special and to see if they will be too comfortable not to make more good preparation so that they can take advantage of that and strike them had than they ever expected and that's exactly what I feel in the statement made by the PSG coach regardless of the form of Arsenal this season. PSG has a very good record this season being the winner of the Ligue1 and one of the teams with less defeats in the league this season I think Arsenal should also be mindful of them because they have a very good squad and the attackers are also in good shape just like the ones of Arsenal, any mistakes from the Arsenal side can lead to PSG defeating them in London and that will be a big blow to Arsenal because of they can't get a good result at home going to France for the second leg to get victory will be difficult.
