Asking for more money...

[KarlMac]

Straightforward question, I've been offered a position at a different company with a slightly improved salary and a bonus. The new role is very much a greenfield role where there is a lot of work needs to be done, where I am now is a large global organisation where everything is controlled by process and I feel I'm very much treading water.

The new role does appeal to me as I really enjoy a challenge, and being honest, I enjoy opportunities to show my skills.

My question is twofold - given the salaries are so similar, what is the 'correct' way to speak to my current employer about reviewing my salary OR what is a professional way to ask my potential employer to increase their offer?

Interested to hear peoples thoughts/opinions on the matter
