Diego Simeone's side saw their 100 per cent LaLiga record come to an emphatic end against Real Sociedad last weekend, while they rallied on Wednesday to secure a 2-2 Champions League draw with Juventus.
100% - Rafinha Alcántara has succesfully completed all his passes (28 of 28, 16 in the opposite half) in the first half vs Atlético de Madrid. Premium#LaLigaSantander @LaLiga pic.twitter.com/wPg5WgiRkl— OptaJose (@OptaJose) September 21, 2019
However, their efforts in clawing back a two-goal deficit against the Serie A champions appeared to have taken a toll judging by their performance against Celta, with a sluggish Atletico failing to score at home in league action for the first time since May 2018.
Hector Herrera was rewarded for his equaliser off the bench in midweek with a first LaLiga start, while Simeone also selected Angel Correa in an attack-minded starting XI.
Yet for all their exerted efforts going forward, Atletico were unable to find a way to beat the outstanding Blanco.
He kept the home team at bay with a trio of fine saves in the first half, starting with an acrobatic effort to turn away Felipe's header from Kieran Trippier's inswinging free-kick.
The visiting goalkeeper also tipped over a rising long-range drive from Renan Lodi, with Blanco then denying Joao Felix's on-target prod from the resulting corner.
Koke tested the 24-year-old reflexes again from distance early in a second half where Atletico became increasingly frustrated with each passing minute.
Lodi's decision to go for goal from a tight angle rather than cross for the waiting Alvaro Morata summed up a below-par performance, while they were grateful substitute Pione Sisto failed to do better with a back-post opportunity in the closing minutes of a quickly forgettable encounter.
What does it mean? Sluggish Atleti come up short
After two tough fixtures, it is perhaps understandable Atleti were a little flat, despite the best efforts of a raucous home crowd to inspire their team.
Worryingly for Simeone, they have now managed just five goals in as many LaLiga outings in 2019-20, despite having 20 attempts on Saturday.
Blanco makes a point for Celta
The away team were resilient in defence but still relied on their goalkeeper to pick up a point on their travels. Blanco made five saves in total, the best of them his early denial of Felipe's close-range header.
Joao Felix fails to fire before departure
The Portugal international has still managed just the one goal for the Spanish club since his big-money arrival from Benfica. As was also the case against La Real, the teenager was withdrawn when his side were searching for a way to find a breakthrough in attack.
With a midweek round of fixtures in Spain, Atletico Madrid travel to Real Mallorca on Wednesday. Celta, meanwhile, are in action the following day, as they host Espanyol.
