Diego Costa marked his comeback with a goal as Chelsea overcame an obdurate Hull City side 2-0 on Sunday to surge eight points clear at the Premier League summit.
Asked about Costa’s display by the BBC, Conte said: “I am happy for him and to finish this speculation (about his future). He played and played very well.
Diego Costa and Gary Cahill’s goals defeated Marco Silva’s side in a hard fought match, but there are still concerns over Mason’s condition, with Conte wishing the former Tottenham man a speedy recovery.
Mason was stretchered off in an eight minute stoppage and replaced by David Meyler in the 21st minute as the fourth official was forced to add on nine added minutes in the first half.
“We are in the second part of the season. Every game is now very tough for us and also for the other teams.”
Marco Silva’s Hull remain in the relegation zone, their disappointment compounded by injuries to Ryan Mason and Curtis Davies, the former being taken to hospital after an aerial collision with Cahill.
“Chelsea had more ball possession, but our team tried and conceded in the last minute of the first half, which was cheap,” Silva told Sky Sports.
“It was a good performance, but I want more.”
