After a highly productive summer where we saw over £1 billion spent by clubs on signing new players, tonight we see the first round of the Champions League and each club will be hoping to start the campaign with a win. Many clubs have acquired new attacking talent and we’ve taken a look at some of the players who will be on show tonight.Arsenal – Lucas Perez
Arsene Wenger signed Lucas Perez from Deportivo for a reported fee of £17.1 million. Arsenal fans will be hoping that Perez will continue his goal scoring form from last season and help them progress further than the last 16 of the competition for the first time in five years. He's in-line to start tonight after making his debut against Southampton and you can currently get odds of 9/1 that he’ll score the first goal against PSG.Atletico Madrid – Kevin Gameiro
Diego Simeone signed Kevin Gameiro from Sevilla for a reported fee which could rise up to £35 million. Gameiro opted for a move to Atletico over Barcelona because he didn’t want to sit on the bench. He scored a penalty on his debut in extra time and with an impressive record in Europe for Sevilla, he’s 4/1 to score the first goal against PSV.Napoli - Arkadiusz Milik
Arkadiusz Milik made several outstanding performances at Euro 2016 for Poland which prompted Napoli to pay a reported fee of over £30 million for his services from Ajax. After scoring two goals against AC Milan, Milik is already a fans favourite in Naples and he has been priced at 7/4 to score anytime against Dynamo Kiev.Celtic – Moussa Dembele
Moussa Dembele joined Celtic on a free transfer in the summer from Fulham. Dembele has already got seven goals in eleven appearances in all competitions which includes a hat-trick against Rangers in the Old Firm derby at the weekend. Demeble will be full of confidence going into arguably the biggest game of his career and bookmakers are offering 6/1 on him to score at anytime against Barcelona.
