Chelsea's Radamel Falcao, Diego Costa can play together - Thibaut Courtois

Radamel Falcao is capable of succeeding at Chelsea and can form a fearsome on-pitch strike partnership with Diego Costa, his Stamford Bridge teammate Thibaut Courtois believes.

Falcao, 29, has joined the Premier League champions on a season-long loan from Monaco, having struggled in his first year in England last term while on a similar stint at Manchester United.

The Colombia striker scored only four goals for United in a campaign blighted by injury and a loss of the form which had once made him the most coveted striker in Europe from his spells at Porto and Atletico Madrid.

Spain international forward Costa moved directly from Atletico to Chelsea last summer, and immediately established himself as one of the Premier League's top players by scoring 20 goals as the Blues' lone front man.

Courtois, who played alongside both Falcao and Costa at Atletico, believes that the pair can both thrive at Stamford Bridge were coach Jose Mourinho to field them in a two-man attack or rotate them as the spearhead of the attack.

"First of all, the manager will put the starting 11 together and see who is playing with who," Courtois told NBC.

"I know Falcao very well. He is a top player... He had his injury one year ago, and at Manchester United, he was maybe unlucky and maybe needed some confidence, but I think if he is on top form, he will add a lot to this team and score a lot of important goals for us.

"If he has to play together with Costa, it is not a problem at all. I remember when we beat Real Madrid in the Copa del Rey, the third goal was a dribble from Falcao in midfield and a pass to Costa, who finished it.

"They know how to play together, and I hope it works and all of the squad will have an amazing season, and in one year, we can look back happy and add some more trophies to our list."

Courtois, 23, added that he needed time to adjust to playing in the Premier League himself when he finally made his Chelsea debut last season after spending three years on loan at Atletico, deposing Chelsea stalwart Petr Cech in the process.

"In the box you are fighting," he said. "It is difficult for a goalkeeper. You have to be strong, and I think I handled it very well. I am strong on crosses and corners. I think I did that very well, but, of course, you have to be strong for every second.

"You cannot lose your concentration for one second because things can change quickly in a Premier League game. Even when a team is losing 2-0 or 3-0, they still do everything to come back until the last second, and you can never relax. You always have to pay attention, and they could come back. Then you are in trouble."

The Belgium international also revealed that his main idols as a young goalkeeper were ex-Real Madrid captain Iker Casillas -- who left the club this summer after spending his entire career at the Bernabeu -- and former Manchester United and Juventus No. 1 Edwin van der Sar.

"For [Casillas] to be playing in goal at the age of 18, it was an inspiration that there was a goalkeeper around at such a young age and he was already important at a big team," he said. "As well, Edwin van der Sar. When he was playing at Manchester United he was a role model because I think I have quite a similar style to him.

"Obviously, you would try to see with your eyes and try to learn from things he did in the game and analyse how he reacted to certain situations. For me, you look at every goalkeeper and you try to learn what they do."
