Barcelona legend Hristo Stoichkov has penned an open letter to Philippe Coutinho.
The former Liverpool ace is struggling for form this season and there is talk he will seek to leave over the summer.
Writing in Mundo Deportivo, Stoichkov stated: "I am writing these words to send you my sincere support for the irregular moment you are going through, although many would like to go through these situations and score two goals as important as you scored against Sevilla in the Copa del Rey.
"The club is not an easy club and I, in my early months, also struggled. I know what it feels like when things do not go the way you want, but I am convinced that with work and sacrifice you will move ahead, because you have everything in quality. You are one of the best foreigners who has ever gone through Barça.
"You should never be discouraged because, from what I've seen, the fans are with you and they really want you to succeed. Think of them as the best fanbase in the world and they will always support you, as they did with me.
"Finally, a small favour. Do not even think about changing teams, as I have read these days could happen. There is no other club like ours. It's more than a club."
