John Terry believes Michael Owen could be a threat to Chelsea winning their first BPL title since the 2005-06 season.
"I'm sure playing for Manchester United and training with those players day in, day out, will mean he is only going to score goals, which I must say is a bit of a nightmare for me as a Chelsea player because I want to win the league and get the trophy back off Manchester United," Terry told the London Evening Standard.
"He only played 12 or 13 minutes against us in the Community Shield, but he still showed glimpses of what he can do."
Terry is confident that if Owen makes a successful comeback with the Red Devils, a call from England coach Fabio Capello will be a given.
"We all know he can finish, we all know he works hard and the qualities he possesses. Can he play in the World Cup? 100 per cent, yes," added the England defender.
"I think the manager has said that there are places for anyone in the squad, not just Michael, if they are playing well or scoring goals."
"The manager is not going to be able to overlook things, if he is playing well, he will have to pick [him]."
