Baba Rahman may not be a player known to many outside of Germany, but the young defender was highly admired by Chelsea boss Jose Mourinho.
However, it looks as though Mourinho will not be adding the 21-year-old to his wealth of young talent at Stamford Bridge, as the Ghanaian looks set to complete a move to Roma.
According to talkSPORT, the Augsburg man had concerns over a lack of first-team football if he moved to London, so has instead chosen to enter negotiations with the Italian club.

Chelsea are not short of talent in the full-back positions with Branislav Ivanovic and Cesar Azpilicueta ever present in the starting 11 as Mourinho’s side stormed to the Premier League title.
With rumours circulating that Filipe Luis will return to Atletico Madrid after one season at the Bridge, Rahman could have been seen as a suitable back up for the first choice pairing.
However there would be strong competition for places with Kurt Zouma able to fill in across the back line and the return, from a loan spell, of highly rated Dutch defender, Nathan Ake, who is entering a make or break period in his Stamford Bridge career.
When comparing the young defender to Chelsea's current full-backs it is clear to see the potential that has attracted interest from some of the top clubs in European football.
The Bundesliga may be a less physically demanding league than the Premier League but Rahman completed more successful tackles than Azpilicueta and Ivanovic, created more chances than the Spaniard and also assisted more goals and won a significantly higher amount of aerial duels than the 25-year-old.
The Ghanaian international, who has made 11 appearances for his country, was also attracting admiring glances from North London with Arsenal rumoured to be interested in his services. However he looks set for a spell in Italy following the promise of more first team football.
However, it seems Arsenal have now turned their attention to Napoli's Faouzi Ghoulam as they continue their pursuit of a new full-back.
The news of Rahman's decision may come as a disappointment to Mourinho as he continues to look for ways to strengthen his squad for a title defence, but it could also be a mistake from the young man, passing up an opportunity to work with one of the greatest managers of all time.
Chelsea are in prime position to capitalise if there was any problems between Rahman and Roma but if the deal was to go through the Londoners could be missing out on of the brightest young defenders in European football.
