I'm glad I am not the only one looking for help with this tactic! I love the idea and theory behind vertical tiki taka - I'm striving for a Sarri at Napoli style of football. I am ten games in to my first season with Eintracht Frankfurt in the Bundesliga and on the face of it I have done pretty well. 7th in the league with 3 wins from 6, only losing to Dortmund and Leipzig, beat a lower-tier team 11-0 in the cup first round, lost the Supercup on pen to Bayern after a 1-1 draw, and lost to Chelsea and drew against a Czech team 0-0 in the Europa League.
Defensively we have been outstanding, only conceding 6 goals in 10 games and keeping 6 clean sheets. But offensively we have been fairly awful. Taking away the 11-0 win, we have scored 5 goals in 9 games. When I checked the stats for the league we are right up there with possession, shots, etc (as you'd expect for this tactic) but we can't score for toffee!! I've tried playing with different formations, even going three out and out strikers for the last 3 games (two 1-0 wins and a 0-0) but we can't seem to tuck chances away. The biggest issue I have, as with the OP, is getting the ball in to the strikers in the box. The midfield knock it about and eventually, more often than not, just try pot shots (despite having 'work in to the box' selected). I have used the preset on default for most games, but have tinkered for the last two or three but changing 'underlap' to 'overlap' and adding 'early crosses' to encourage attacking wing-backs to get the ball and ping it in quick. It has helped a little I think, but not as much as I hoped.
Any ideas on what I could do differently? Up the tempo and directness perhaps? Introduce an advanced playmaker in the 10-hole? I'd be fascinated to hear from anyone that has had success with the vertical tiki taka preset, especially with a similar sized club (Everton/West Ham/Valencia/Hoffenheim-type clubs, etc.).
Thanks in advance for your help.
