Middlesbrough head coach Aitor Karanka has challenged loan signing Danny Graham to rediscover the form which saw him terrorise Championship defences.
The 28-year-old scored 24 league goals for former side Watford during the 2010-11 season to win a move to Swansea, but has managed just one in his last 38 appearances for the Swans, Sunderland, Hull City and first club Boro, for whom he made a second debut at Doncaster last weekend as a substitute.
Karanka told the club's official website: "He grew up here, he knows the club and he knows the people.
"He is a player who improves our squad and if he is confident, he will score a lot of goals.
"He is training well, but he needs more time as he hasn't been playing recently.
"He might not be fit enough to play 90 minutes, but I think he is a player who will help a lot in the future."
