While not ITK, we can make some general assumptions here.
1. I’d say something in the middle of our earners. He should be on more than say the squad members unlikely to start 5 games (Foderingham, Rodwell, Jags etc). He should probably be on more than Bogle & Lowe. He probably should be on something similar to or marginally above what Osborn is on. He should not be on the wages that our likely first choice starters are on (people like Egan, Basham, Baldock etc), and certainly not in the 20k plus bracket that McBurnie, Berge and Brewster will I’m sure be on.
2. It’s fair to say given when he signed, even taking into account the % rise after promotion, that he will be one of the lowest paid in the squad – and certainly the lowest to have played 15+ games last season.
3. I reckon he’ll have been offered something that would put him about in the middle of the squad in terms of earnings. He probably thinks he can earn more than that as a backup elsewhere in the Prem, or first choice in a Championship team. And that might be true.
