Eintracht Frankfurt is beatable but so are Arsenal and it will be whoever gets the basics right and does their jobs properly that will emerge the winners.
We all saw what went wrong against Watford and to some extent, Tottenham and Arsenal simply have to avoid a repeat of those games.
Here are five simple things that Arsenal have to get right if they want to beat the Germans today.
Must stop them down the flanks
Eintracht are strong down the wings, they will look to exploit Kolasinac and Maitland-Niles because you just know that the Germans will have done their homework and know that is where Arsenal are weak. The Arsenal wing-backs must do their jobs properly today or it will be another depressing match for Arsenal fans.
Midfield must stop attacks getting to the defence
The midfielders have to do better than they have been doing, the defence is under such pressure because the opponents are just swanning through the Arsenal midfield, they have to break up attacks and frustrate the opponents and make life easier for the defenders.
Forwards must trackback
This applies specifically to the wingers, probably Pepe and Nelson, they have to track back and help out the likes of Kolasinac and Maitland-Niles, they have not been doing so and that has left the full-backs fully exposed.
Heads cannot drop
If things go wrong the players have to show character, they cannot allow another capitulation, they have to bounce back far better than they did against Watford. In better words, time for them to stand up and be counted.
Must find a plan B
Unai Emery has to find a plan B, if short passing out the back is failing then do something else, if the defence is being overrun then do something else, slow the game down, employ spoiling tactics, anything is better than sticking with tactics that is not working.
