Alexander Hleb has apologised to the people of Birmingham City for his mediocre performance this season.
The Belarus international spent the campaign on loan at St Andrew's from Catalan giants Barcelona but was well below his best mainly due to a variety of injuries.
Hleb has stated that he will not be returning to the club next season but has said sorry to the fans ahead of his departure.
"It has been difficult. I came to this club with ambition and wanted to give my best for Birmingham City but the injuries have been bad," he said.
"I haven't shown everything that I know I can and I'm sorry for that. I wanted to give more but I can't change what happened.
"But I have enjoyed my time, it's been a new experience here in Birmingham for me.
"I want to say a thank you to everybody linked to Birmingham City. I have been given the opportunity to understand the big history of this good club, I've learned a lot.
"I fully respect the fans and every single player because these people have done a lot for me."
Hleb also said that he feels the club is too good to be playing in the Championship and is urging his teammates to produce a winning performance over Wolves on Sunday.
"We want to stay in the Premier League," the former Arsenal star added.
"I don't care what happens in the game on Sunday and how we do it but we need to win against Wolves.
"It is a very important game. It's my birthday and if we win it will be the best present for me. I'll be doing everything to make sure that happens.
"I believe 100 per cent that we will stay the Premier League. We're good enough to stay and play in this division."
