Statistically speaking, Barcelona has a better H2H record against Atletico Madrid but considering the current form of both teams in all competitions, it's obvious that Atletico Madrid has a better record. In Atletico Madrid's last 11 games, they've been formidable enough not to lose before going into their league fixture against Barcelona but because Barcelona will be the home team, I expect a difficult game for both teams. My prediction is that the away team in will either get a win a leave Camp Nou with a point.
In terms of h2h, Atletico seem far inferior to Barcelona, even in the last 5 matches Barcelona have always dominated and won consecutive wins over Atletico, so this could be a good motivation for Barcelona to continue their dominance over Atletico.But when talking about the statistics of the last few matches, it is clear that Atletico are now more solid for the continuation of La Liga and Barcelona are now still like a club that struggles to maintain consistency and performance, especially 1 win, 2 draws and 2 defeats, obviously it is not a good record for Barceclona so I think Atletico's chance is still very big by looking at their statistics in the last few matches.
It's just that this is a big match where all situations can happen, we take the example of El Clasico where a big win happened and there could be surprises again in this big match because after all the defeat and victory will determine for both teams in the standings.
