ARSENAL have a positive omen going into this evening's huge match against Paris Saint-Germain. The Gunners host PSG in the first leg of the Champions League semi-finals at the Emirates Stadium. They previously hosted the Ligue 1 champions in the group stage six months ago. Goals from Kai Havertz and Bukayo Saka saw Arsenal win 2-0 at home. Mikel Arteta will now be hoping for a similar result tonight. And the Spaniard has received what many superstitious fans may consider a good omen in the build-up. Slavko Vincic - the man who officiated the last match between Arsenal and PSG back in October - will be the referee tonight. The Slovenian did not have much to do last time out at the Emirates, only handing out yellow cards to Riccardo Calafiori and Fabian Ruiz. PSG have massively improved since then, with the likes of Ousmane Dembele, Bradley Barcola, Desire Doue and Khvicha Kvaratskhelia all on top form. However, the Gunners have reason to be confident following their 5-1 aggregate win over reigning champions Real Madrid in the quarter-finals.

He said: "I tell them [the supporters], and I’m not exaggerating here: ‘Guys, bring your boots, bring your shorts, bring your T-shirts and let’s play every ball together. "We want to do something special. The place has to be something special, something that we haven’t seen. "I really hope that everybody that comes to the Emirates and is watching and following us, brings that energy with them."
