Chelsea's strikers will love playing with Juan Cuadrado if he does join, says Thierry Henry.
South Korea international Ki Sung-Yeung is set to complete a season-long loan move to Sunderland after heading for Wearside.
Press Association Sport understands the Swansea midfielder travelled to the north east on Friday night and is due to undergo a medical on Saturday morning.
Ki would become manager Paolo Di Canio's 12th summer signing with Monday's summer transfer deadline fast approaching.The 24-year-old started his career at FC Seoul and moved to Europe when Celtic gave him his big chance in January 2010.
He won the Scottish Cup and league during his time at Parkhead, prompting the Swans to invest a then-club-record £5.5million to secure his services in August last year.
However, just 12 months into a three-year deal, he finds himself surplus to requirements at the Liberty Stadium and that has allowed Di Canio to strengthen his central midfield resources.
Sunderland are in action at Crystal Palace on Saturday evening where they will look to impress Ki by building on their midweek cup win over Milton Keynes.
Di Canio's men also drew at Southampton last weekend but know they are in for a tough examination against Ian Holloway's Palace.
Both Holloway and Di Canio are renowned for their passion, and Holloway has struggled to date to fulfil his vow to hold his tongue since his return to the top flight, where he previously enjoyed a colourful spell in charge of Blackpool.
However, Di Canio insists there is far more to his latest adversary.
He said: "I like Ian, I have followed his career because I like to know my colleagues.
"He has experience - Bristol Rovers, Queen's Park Rangers... He has had some defeats in his life, but he has done a fantastic job, in my opinion. The balance is more on his side.
"Sometimes people - it happened to me when I started just two years ago - focus their attention on the passion and the body language, and probably they underestimate his tactical skill.
"He is good, but it is clear also that the players have taken up part of his character.
"I like him. He's a good character with good tactical skill - but obviously I am going to play against him and I hope my team is going to win."
