Chelsea manager Jose Mourinho has vowed to get striker Radamel Falcao scoring again.
The Colombia international, who will spend the 2015-16 campaign on loan at Stamford Bridge from Monaco, struggled for form during a temporary spell with Manchester United last season.
Falcao, 29, scored four goals in 29 appearances for the Red Devils, who decided not to keep him at Old Trafford for another year.
The forward has battled against persistent injury problems in recent seasons, but Mourinho is confident that he will rediscover his form while playing for the Premier League champions.
"We had a very exhaustive analysis of his condition before we made a decision," he told ESPN. "Our doctor had real work to investigate all of that. He is not, for sure, a physical problem. So if it's not physical, we can make him score goals again.
"When he went to Man United I have to say I was a bit scared, because he's a predator in the box and a guy who does score goals all the time. He did that in every club in every league, so I was convinced he was going to do that in our league, in England."
Chelsea's pre-season campaign continued on Wednesday with a penalty-shootout victory over Barcelona in Washington DC.
