Over the last few weeks, I've been emotional about leaving a club that is family. After 22 years I’ve had so many special memories and moments that I will cherish forever. @ManUtd will always remain in my heart. A massive thank you.

He said:"I was on autopilot. I was having conversations with people, and I was just like: 'Yeah. OK. Yeah.' Nothing would register. It would go in one ear and out the other. I was numb, and I wanted to be in that numb state, where I didn't have to feel anything."Lingard, who registered 35 goals and 21 assists in 232 games for Manchester United, said that he resorted to coping mechanisms such as alcohol, as he was lonely. He added:"Literally, I just wanted to sit at home and drink a little bit – try and take the pain away. I don't do that, normally. But sitting at home and drinking before bed. ... that's when I knew I was in a bad situation. I look back and think: 'What was I doing?' Because I didn't have anyone to bounce off or feed off, I resorted to that."Shedding more light on his struggles, Lingard concluded:"Nobody really knew about my struggles off the pitch, so they think: 'You're a footballer; you live in a nice house; you've got money; you can deal with anything.' But when it's someone's health and well being – it's a different situation. We're all human."Jesse Lingard@JesseLingardBout time top team performance tonight, thank you to the fans for your support #Jlingz #griddy12967851Bout time 😅 top team performance tonight, thank you to the fans for your support ❤️ #Jlingz #griddy https://t.co/UKtYukFD9CLingard, who helped the Red Devils lift four trophies during his stint, has scored one goal and laid out an assist in 14 appearances across competitions for Nottingham Forest this season.Manchester United star on radar of three Premier League clubsAs per reputed journalist Rudy Galetti, Leicester City and two unnamed Premier League clubs are interested in signing Manchester United captain Harry Maguire this winter.Maguire, 29, has been phased out of the Red Devils' first team this season due to his error-prone displays in the backline.
