Cesc Fabregas has admitted it was difficult to watch Arsenal lose so heavily to Manchester United but has backed his former team to recover from the disappointment.
The Gunners endured one of their darkest days in recent history with an 8-2 defeat at Old Trafford on Sunday, as the likes of Wayne Rooney and Ashley Young ran riot.
Arsene Wenger was only able to field a weakened team due to injuries and suspensions, while Samir Nasri had recently gone to Manchester City and Fabregas joined Barcelona.
Fabregas has promised to keep an eye on Arsenal from afar and he was pained to see they were pummelled so mercilessly by the Red Devils.
The Spanish midfielder nevertheless hopes they can bounce back as he insists the club will always hold a special place in his heart.
"I watched the match against Manchester United on television and it was difficult," he told El Mundo Deportivo.
"I suffered during this match and especially because of the enormous rivalry between the clubs.
"But I am convinced that the squad will improve for the next matches.
"I will always have important feelings with the Gunners. I am a fan through the good and bad moments."
Fabregas also paid tribute once again to Wenger, who helped him to develop into a world-class player during his time in North London.
"I hope that I can transfer the lessons Wenger has taught me to my new work at Barca," he said. "I will always be grateful to the coach."
