Caterham's Mike Gascoyne believes that former driver Heikki Kovalainen should have paid more respect to the team.
Kovalainen raced with Caterham from the start of their F1 journey as Lotus Racing in 2010 until the end of 2012. The Finn remains in the running for the 2013 seat, but it is thought unlikely that he will be in the sport this season.
Gascoyne, who is now the Chief Technical Officer for the Caterham Group believe that Kovalainen's management should have handled the situation better.
"It is actually a great shame", he told Crash.net.
"Heikki is a very talented driver but, last year, his management did not handle him very well and he has not done himself any favours. It is a tough environment out there for everyone. He has had three years with Caterham, was paid well, and he should have shown more respect about that."
Gascoyne also added that ensuring Caterham's long term future is vital before pushing on in Formula One.
"Maintaining our position as a tenth place team will be the priority, but what is important is the automotive development of the Caterham Group. If the group is profitable, then the Formula 1 project will have a long-term future."
Caterham has fended off both Marussia and the now defunct HRT for tenth place in the championship across three successive seasons. French driver Charles Pic joins the team on a multi-year deal, with the identity of his team-mate yet to be announced.
