The showdown is between two European heavyweights. And tactics, formations and the starting XIs are certain to play a part in who comes out on top in the Champions League final in Budapest.In the red corner are the unbeaten challengers. Arsenal have yet to lose a game in the competition this season but Mikel Arteta ’s men face the ultimate test on Saturday.In the blue corner are the reigning champions and arguably the best team in the world right now which is why they surely enter the contest as favourites. They blew Inter Milan away in last season’s final with their fast, free-flowing football which was led by Ballon D’Or winner Ousmane Dembele.This will be a clash of styles. Attack versus defence. Plus some selection dilemmas and injury doubts. Will PSG risk Achraf Hakimi? Can Arsenal really start Jurrien Timber for his first game in more than two months? It could be teenager Myles Lewis-Skelly in midfield ahead of Spain international Martin Zubimendi.‌Here, we look at who might start - and who might come out on top as the European giants go head-to-head.FOLLOW OUR ARSENAL FB PAGE! Latest Gunners news and more on our dedicated Facebook pagePSG (4-3-3)Matvéi Safónov 6Hard to understand Luis Enrique ditched Gianluigi Donnarumma for Safonov… but they did. And it’s a weakness. Achraf Hakimi 8‌The Morocco full back is one of the best in the world but his fitness has been a huge talking point. They might risk him - but he’s a doubt. Marquinhos 7Experienced and top quality defender who leads the back line and is the defensive kingpin. Reliable. Willian Pacho 7The Ecuador defender is quick, mobile and vocal. He plays a high line with PSG but is rarely undone. Nuno Mendes 8Another key man for PSG. Their full backs are so important because of what they offer on the break. Sensational player. Joao Neves 7‌Beautiful player, elegant and classy. A real snip at £60m from Benfica, he is so important for their midfield trio. Fabian Ruiz 7Spain international who is busy in the midfield engine room. Classy on the ball and fantastic passer with great energy. Vitinha 8Remember him at Wolves? No. Nor does anyone else. Could barely get a game. Now he runs the best midfield in Europe. Desire Doue 7This position is not nailed down but his energy, pace and recent displays have made him the favourite to start. Khvicha Kvaratskhelia 9‌Arguably the best winger in the world right now. The Georgian is a national hero. With his socks rolled down and dribbling style, he’s a throwback. Ousmane Dembele 9A superstar up front. He will be fit and he is lightning, direct and Arsenal need to stop him at all costs. Ballon D’Or winner.MANAGER: Luis Enrique 9A glittering career as a player was followed by huge success with Barcelona as a manager and that puts him on a different level.‌With PSG, he has built arguably the best European club team since Barcelona’s team of Messi, Iniesta, Xavi and Co. They are brilliantly exciting and were so clearly the best club team in the world last year.Arsenal (4-3-3)David Raya 8Is making a play to be the best keeper in the world. Great reflexes, plays out from the back and s a huge advantage for Arsenal. Jurrien Timber 7‌This is the big one. A fully fit Timber is a great asset. One who has not played in two months is a risk. But it’s him or Mosquera. William Saliba 8What a classy defender. Saliba is so strong, confident on the ball and composed. One of the best in the world. Gabriel 8An absolute menace in both boxes. A threat in attack and a tower of strength in attack. A great asset for Arsenal. Riccardo Calafiori 7This one is not set. It is him or Piero Hincapie and who platys may depend on Timber to ensure good defensive balance. Declan Rice 9‌Arsenal’s best player this season, the best player in the Premier League and he is absolutely up for the challenge. Myles Lewis-Skelly 7Yes, you read it right. Ahead of Martin Zubimendi. He is playing well enough, it is a gamble but he’s got momentum. Martin Odegaard 7His quality as a player and a leader means he will probably get the edge over Eberechi Eze. A big challenge - but he’s up for it. Bukayo Saka 8This has not been his best season but he is a big game player, vital for club and country and such a threat when providing chances. Leandro Trossard 7‌In European games, Trossard is Mikel Arteta’s go-to man. He is skilful, great in tight spaces and almost better in Europe. Kai Havertz 7He has scored the winner in a Champions League final and may get the nod over Viktor Gyokeres who probably gets the role as “finisher.”MANAGER: Mikel Arteta 8A great tactician, he is aspiring to become the next Enrique in managerial terms and therefore must start as the underdog in this toe-to-toe.‌Arteta is clearly more pragmatic but now has this incredible opportunity to become one of the great managers of this era. That is why he is so close to Enrique - but is the manager-in-waiting.TOTALSPSG: 92Arsenal: 91Join our new WhatsApp community and receive your daily dose of Mirror Football content.
