Chelsea striker Diego Costa and defender Gary Cahill will be fit to play against Arsenal in the Community Shield at Wembley tomorrow, manager Jose Mourinho has said.

Spain striker Costa limped off with a hamstring problem in a pre-season friendly against Barcelona in the US, while Cahill suffered a suspected broken nose after scoring an 85th-minute equaliser against the Spanish champions.

“All good, yes,” Mourinho told a news conference yesterday when asked about the fitness of Costa and Cahill.

Costa scored 20 league goals for Chelsea in his debut season at Stamford Bridge after joining from Atletico Madrid for £32 million, but the striker missed large parts of the campaign with a persistent hamstring problem.

Mourinho, however, has no long-term concerns over the 26-year-old’s fitness and says Loic Remy and Radamel Falcao will provide Costa with stiff competition during the season.

“No concerns, I am not worried about it,” he said. “We have three top strikers. If one is injured we have two more.”

The Community Shield, the traditional season-opening match between the Premier League champions and FA Cup winners, has lacked spark on occasions but Mourinho believes the fixture is more than a pre-season friendly.

“It is in between,” said the Portuguese, who has not lost to Arsenal manager Arsene Wenger in 13 meetings.

“It is not a friendly... it is more than that but less than a Premier League match.”

“I just want my club to get the best possible result. It doesn’t matter about Arsenal, it doesn’t matter about the manager.”
