He doesn't get any service from his teammates and is being left out from the starting lineup in all big games (CL, FA Cup ) =Frustration. He barely got a run of 3 full 90 minutes this season, being benched or substituted constantly when he didn't immediately start to score. His frustration is actually quite obvious. Basically criticising di Matteo's tactics against Bayern even after just winning the CL for the first time (Well, I think we need to attack. We played all game with the handbrake on, looking like we couldn't attack. I think we could. Defending compact ok, but also attacking.
Cameras were also showing him looking disgusted when Drogba was rolling around on the floor at SB against Barca. He's not in the right environment .
Drogba is at 13 goals in all competitions, Torres at 11. With Torres spending a lot of time on the wings and nonsense like that. That poor record can't be down to both strikers
A world class striker doesn't turn into total garbage overnight with 27. He had some injuries but nothing too serious he couldn't recover from at his age. His last injuries were back in 2010 if I recall correctly. Players like Iniesta and Robben have had far more muscle injuries than this guy. He definitely didn't lose any pace. He still looks very fast and all.
