Teenage Genk goalkeeper Thibaut Courtois will undergo a medical ahead of his transfer to Chelsea, Blues manager Andre Villas-Boas said Monday.

Villas-Boas said the two clubs came to an agreement on Sunday for the 19-year-old player. The fee has not been disclosed but is reported to be about 8 million pounds ($12.9 million).

After arriving in Malaysia for the start of Chelsea's preseason tour, Villas-Boas said Courtois would not be joining the squad in Asia.

The former Porto manager, meanwhile, said he is hopeful of guiding Chelsea to the Champions League title. Villas-Boas replaced Carlo Ancelotti, who was fired in May when the Blues finished the season without a trophy.

''The prize is the Champions League. If you look at the last several seasons, you will see the same teams challenging for it,'' Villas-Boas said.

Acknowledging the pressure to win silverware, he said, ''Any person that sits in the manager's job at Chelsea is expected to win and I don't run away from that.''

Villas-Boas said he had no ''urgency to sign any players at this moment,'' despite reports linking Chelsea with Tottenham midfielder Luka Modric.

All players will have to prove themselves, including 50-million-pound striker Fernando Torres, who only scored once in 18 appearances after joining Chelsea from Liverpool in January, he said.

''It is not a question of what I can teach the team but what the players can show me they can do,'' Villas-Boas said.

Chelsea star midfielder Frank Lampard seemed to agree with his new manager's approach.

''Manchester United, Man City and Liverpool have spent fortunes on good quality players,'' he said. ''But I think we are in a bit of a different situation because I think we already have a very strong squad.

''The manager obviously wants to evaluate what he's got, which is very understandable, and who knows whether we add or change, that's the manager's prerogative.''

Following a match against a Malaysian XI in Kuala Lumpur, Chelsea will travel to Bangkok to play a Thailand All Star team and then to Hong Kong for two matches.
