Glen Johnson believes Jadon Sancho's permanent move to Chelsea next summer is a "completely one-sided deal".

The Blues have an obligation to buy Sancho, who is currently on loan in west London, from Manchester United at the end of the season for around £25million, football.london understands. The 24-year-old has had an outstanding start to life at Stamford Bridge and has scored two goals in his last three Premier League matches for Chelsea.

Sancho's latest outing, in the win versus Brentford at home on Sunday evening, produced another impressive display from the tricky winger. The United loanee can count himself highly unfortunate not to come away from the match with his sixth assist of the season, after putting the ball on a plate for Nicolas Jackson, who fired over from close range.

Johnson, formerly of Chelsea, has been speaking to Betfred about how well Sancho has been doing for the Blues recently and how he feels his old club are getting the much better end of the deal. "Jadon Sancho's move from Manchester United looks like a completely one-sided deal," Johnson said. "These days, £23m for a player like that, it is like giving him away.

"What he's done in the last few weeks is what we know he's capable of, but he just needs to do it more often. He looks like he's enjoying himself and that's why he's putting in performances, so the manager and his backroom staff deserve credit too because these players that weren't performing are now."

Sancho himself is loving life at Chelsea. An unexpected title challenge, albeit with head coach Enzo Maresca not admitting it, has galvanised the squad.

Speaking to the club's official website last week, Sancho said: "We have belief in each other. Training every day together, we know what each other can do and we have big-game players that can change a game around. We stuck to the game-plan against Tottenham and continued to work.

"We obviously have a lot of top-quality players and in training everyone thrives off each other because the intensity is so high and everyone wants to show what they can do. There is competition for places and everyone wants to be starting games, so it's good to have this competition in the squad."

"We're all kind of leaders, because we all have different attributes to help each other, but the leading voice is definitely the manager," Sancho continued. "The manager is the voice of the whole team and whatever he says goes. We all buy into that.

"He understands us and always gives us advice about what to do in our position and how to help each other out. All the players trust him and believe in him. It's always nice to feel supported, but he's played the game as well so has a lot to offer and give advice on, about what to do and not do."
