The 27-year-old insists Diego Simeone's men have enough quality in their side to compete in La Liga, Champions League and the Copa del Rey.
Atletico has had a fantastic term so far: it has sealed progression to the last 16 of the Champions League, had its best start to a La Liga campaign where it currently sits second and booked a place in the quarterfinals of the Copa del Rey following a 3-1 aggregate victory over Valencia.
Injuries and suspensions could take their toll with the more games they are involved in, but Garcia is convinced they can cope with the pressure.
"We are still on the same path as before. We have enough depth in the squad to battle in three competitions which is what we are doing," he was quoted as saying by AS.
The midfielder's header was the clincher in a 2-0 win over Valencia in the Copa del Rey on Tuesday after Diego Godin has initially nodded in the opener.
Following the exertions of a demanding encounter against Barcelona on Saturday, Atletico somewhat struggled to lift itself for los Che, but Garcia says the team was made to work hard and believes opposition will continue to make it difficult for Diego Simeone's men.
"Valencia are difficult opponents in spite of however they are doing in the league. In the end we prevailed and the result speaks for itself," he said. “Yes, it’s fair to say that this was a demanding game for us. We have reached the level where we cannot lose any game and now, that’s what makes other teams want to beat us. But physically, the team is still strong."
