Filipe Luis and Diego Costa were all smiles as they headed to Holland for the next leg of Chelsea's pre-season tour.

Chelsea’s recent recruits Filipe Luis and Diego Costa were able to pose for a picture after a job well done for their new side, as they prepared to travel to Holland.

The duo, both brought from Atletico Madrid this summer, started for the Blues in their pre-season friendly against Slovenian outfit Olimpija Ljubljana.

Chelsea ran out 2-1 winners, with Costa on the scoresheet – netting his side’s first goal of the match with a fine, right-footed finish after latching onto fellow new recruit, Cesc Fabregas’s, through-ball.

It was a goal that delighted his manager who feels that Costa can help his side win the Premier League this season.

“Obviously it's nice for a striker to score in his first game,” the Portuguese boss said.

“We feel we are going to be very strong and we want to fight for the title, no doubt about it.”

Chelsea will now travel to Holland, where they will play Vitesse Arnhem, with Costa and Luis both likely to feature again.

The Brazilian-born duo are both expected to have key parts to play in Chelsea’s upcoming season and will be looking to use this pre-season as a chance to adapt to playing with their new team-mates.

One of Chelsea’s major problems last season was their lack of a clinical striker and Costa is expected to be a solution to that problem after completing his £32 move from Atletico this month.

The front-man, who was part of Spain’s dismal World Cup campaign this summer, scored 27 times for the La Liga champions last season and if he can recreate that total this year Chelsea will surely be in a good position to claim the title.

Luis, meanwhile, will be hoping to fill the void left by Ashley Cole’s departure. The experienced England international lost his place in Chelsea’s starting line-up last season, after being a mainstay for a considerable amount of time previously, and was allowed to move on during this transfer window.

Cole chose to move to Roma, but replacing the fans’ favourite will not be easy and, as such, Luis is under-pressure to become an instant success at Stamford Bridge.

If he can live up to expectations, Luis’ energy and power down the left-hand-side will be a key figure in Mourinho’s starting line-up.

Both will have to step up quickly, though, and the initial signs are encouraging that they are relaxed about the task in hand.

Can Luis and Costa be successes at Chelsea?
