We tried playing 4 forwards 2 seasons ago when Shaqiri played with the front 3 and it just never works because we get overwhelmed playing 2 mids only, I remember that game we switched it up at halftime, I don't think its something we can do tactically as we got away with it in the first half, they had chances to score a 2nd and kill the game. The penalty was scandalous as Fabinho won the ball but second half we improved and found our composure to win the game. The performance was dodgy but the result is priceless with top teams dropping points.
