Romelu Lukaku can take comfort from Timo Werner's return to form and the Belgium star just needs "one spark" to find his confidence again, according to Chelsea head coach Thomas Tuchel.

Werner has come under regular scrutiny following his £45million (€50m) move to Stamford Bridge from RB Leipzig in June 2020.

The Germany international scored six goals in 35 appearances in his debut Premier League campaign and has found the net on just three occasions in the top flight this season.

However, two of those strikes came in the 6-0 rout of Southampton in his last league game, as many goals as he had managed in his previous 27 appearances in the Premier League. Werner also scored at Real Madrid in the Champions League and was influential in the FA Cup semi-final win over Crystal Palace.

Lukaku has endured similar struggles since his big-money return to Chelsea from Inter at the start of the season, last scoring in the league in December against Brighton and Hove Albion.

The former Manchester United man has been hampered by injuries as well, and although he missed glorious opportunities against Madrid and Palace on his return, Tuchel believes he will soon find his form.

"I don't think he needs inspiration as such, but he needs that one moment, that one spark," Tuchel said on Tuesday when asked if Lukaku could learn from Werner.

"He maybe would've been a natural starter against Crystal Palace given the minutes Kai [Havertz] has played and the matches recently, but after a period of injury he lacked the fitness for matches.

"I don't point the finger at him, it's just a fact.

"Compare the difference in Brentford and Southampton, and the two legs against Real Madrid, you see the effort we put into become a winning team and this is what we need.

"Romelu should've had a goal against Real Madrid and Crystal Palace, but if he plays we need all that he has."

Reece James is another who has suffered with injury problems throughout the campaign, but he has shown encouraging form in recent weeks.

Tuchel acknowledged the brilliance of the England international, even if his adaptability causes many a selection headache whether to play him as a right wing-back or third centre-back.

"I think the back three is a little less demanding physically in terms of the wing-back position given he comes from a long injury," the German added on James.

"It is a bit of an advantage to have him in the back three because it is less demanding physically. He can play both positions brilliantly and we can only pick him once, so we have to decide."

Meanwhile, Tuchel expressed his gratitude to the work of Jorginho, who started against Palace on Sunday after being rested for two league games with Southampton and Brentford.

"He sacrificed for the team and I think you see it now," he said of the Italy midfielder. 

"There are so many demands, and after a big success, like winning the Euros, he felt the pressure. This is normal and sometimes after big success it is difficult to keep on going and going.

"He put the responsibility on his shoulders and always does. That is why I love him. We see we overused him and I feel we see the consequences of that. He is not at his freshest moment at the minute."
