I really hope that Hansi Flick modifies Tiki Taka, which is famous for ball possession, with the game pattern he has used since coaching Bayern Munich. The combination of Tiki Taka with fast attacks will certainly make it very difficult for the opponent, when they manage to control the ball, it is very difficult for the opposing players to guess where they will go next. Hansi Flick can take advantage of the running speed of players operating on the left wing and right wing to build fast attacks, this strategy can also make it easier for Lewandowski to rediscover his sharpness.
That is a good strategy if Barcelona can use it next season and I think any rival will find it difficult to beat Barcelona if this strategy can really be used and developed well by Hansi Flick. However, I also have no doubts about the strategy that Real Madrid will still use next season because it is always difficult for any opponent to guess where the ball is being supplied to the players in the front line by the midfield players. I saw this when Toni Kroos gave a pass from the middle to Vini.Jr who ran forward and it was truly extraordinary.
