He insists he has yet to make up his mind whether to sign on at Pittodrie or jump ship but is tempted by a move to England after seeing former team-mates Barry Nicholson and Russell Anderson thrive down south.
Scotland international Severin said: "A few clubs have been on the phone to my agent but he has told them we are still in discussion with Aberdeen and they will be the first club to know my decision.
"I realise a tough decision will have to be made and I will not rush into it. I have a young family to think about and my wee boy starts school next year.
"I am 30 now and this will be the biggest decision of my career so I will take as long as is necessary. I have spent 10 years in the SPL and there are times you feel it is a bit boring and you fancy a new challenge.
"There are other times you realise this is a great league to play in and I enjoy it.
"Barry Nicholson decided to go and has really enjoyed it. Russell Anderson is another player who made the move and doesn't regret it."
