Greg Tansey believes securing Ladbrokes Premiership survival would be a perfect farewell gift for his Inverness team-mates before he leaves this summer.

The English midfielder has signed a pre-contract with Aberdeen and will move to Pittodrie once the current campaign comes to an end.

But Tansey, 28, who won a Scottish Cup winners medal with Caley Thistle in 2014, is determined to leave on a high.

Richie Foran's men are five points adrift at the bottom of the table with only five games to go.

Tansey, however, is not ready to give up on his current club's hopes just yet.

He said: "It was a tough decision to leave here. I've got a lot of friends at the club and in the dressing room.

"It's a place I've grown very fond of - but a new challenge presented itself and after a long couple of weeks thinking about it, I made my decision.

"The lads in there know it's not a question (of me not giving my all). I've been at the club nearly three and a half years and they know I'm not going to down tools.

"I don't want to leave here with a relegation. I'll be doing everything I can to keep us up."

Friday night's Highland derby clash with Ross County in Dingwall is the start of Inverness' make-or-break bottom-six run-in.

And Tansey believes the atmosphere generated by their showdown with their local rivals will be just what his side need as they bid to turn up the heat on closest rivals Dundee.

"The atmosphere is always good in these games," said the former Stockport player. "Although it's a small ground, it's compact and we always take good support.

"Behind the goal is always full and you can hear them all game. They're always good occasions to play in and I think it's one the lads relish.

"We're playing the day before all the other sides in the bottom six, so it gives us the opportunity to put pressure on the teams above us.

"Playing on a Friday, there'll be a lot of clubs looking over their shoulder at us.

"We can't worry about Dundee. They've had a few not-so-good results over the last few weeks and it can be hard to get over.

"We can see it as a positive - win on Friday and it puts pressure on them when they play on Saturday."
