Trinidad and Tobago international striker John, who has struggled to hold down a regular starting place in Steve Bruce's side this season, has been offered a new one year contract.
Belgian goalkeeper Vaesen, who only returned to action towards the end of last year after being sidelined for seven months with a knee ligament injury, is currently on a season-long loan deal with Crystal Palace having had loan spells at both Gillingham and Bradford City earlier this year. Blues are said to be offering 34-year-old Nico a new one year contract with the option of a further year at the end of that period.
Both players current contracts are due to expire in the summer and the club are reported to be waiting on the pairs decision on these new deals.
