Chelsea regret selling playmaker Kevin de Bryune leave, according to Wolfsburg chief general manager Klaus Allofs.
The Belgian international left Chelsea to join the Bundesiga outfit in a deal worth £17 million over the summer, and has been in exceptional form since. He's scored 8 goals and managed 11 assists in the league this season, helping the Wolves into second place behind Bayern Munich.
De Bruyne has subsequently been linked with a move back to Stamford Bridge, and Allofs has conceded he could leave if Champions League qualification isn't secured.
However for the time being the Wolfsburg chief says he is delighted with De Bruyne - and claims that Chelsea feel as though they've made a big mistake by letting the 23-year-old go.
'At Chelsea they watch with appreciation as Kevin has developed,' he told Kicker.
'They've seen it confirmed why they were reluctant to let him leave.'
De Bruyne joined Chelsea from Genk in 2012 for a fee of around €8 million, however he only ever made three league appearances for the Blues, and he spent the 2012/13 campaign on loan with Werder Bremen.
There he managed 10 goals in 33 league appearances, and it was expected that he'd force his way into the Chelsea team for the following season, however that never materialised amidst rumours of a fractious relationship with Jose Mourinho.
The Special One publicly criticised De Bruyne and forced him to train with the Chelsea U21 team after a Capital One Cup game against Swindon in 2013, and the young playmaker hit back after his exit had been secured.
"It’s a pity he told a press conference that I wasn’t doing well on the training pitch,” he said last year. “That’s not me. I’m always a player who gives the full 100 per cent in training. Those remarks created a wrong image."
Given his somewhat acrimonious exit from Chelsea a return seems unlikely. The fact De Bruyne is doing so well since leaving Stamford Bridge is likely to irk Jose Mourinho on a personal level, but the club will still consider the deal as a success.
After all, they made a profit in the region of £14 million for a player who barely pulled on the famous blue shirt - a trick they have been able to repeat with Andre Schurrle and potentially Mohamed Salah if his loan move to Fiorentina is made permanent.
However there is no doubt the De Bruyne is blossoming in Germany, and the Chelsea fans would love to see him strut his stuff in west London once more.
