Norwich City manager Paul Lambert has one more target in the January transfer window – and says negotiations are under way to bring in the player he wants.

The news came as the Canaries agreed to let striker Oli Johnson join League One club Yeovil Town on a month’s loan.

Lambert has already added MK Dons striker Aaron Wilbraham and Colchester defender Marc Tierney to his squad this month, after clinching a permanent deal for West Bromwich Albion defender Leon Barnett back in December. But he wants to complete one final move before the window closes, with Sky Sports suggesting yesterday that Portsmouth midfielder Michael Brown might be the target.

“I’m trying to do one now. There is still a bit of water to go under the bridge before we can say, but I hope so,” he said yesterday.

“I never trust it until he actually walks through the door. Until I see someone physically coming in I won’t believe it. It can blow up within a second.”

Another option for Lambert would be to extend the loan of Arsenal midfielder Henri Lansbury, who was declared fit for selection for the game against Cardiff today after missing three league matches with a hamstring injury. His loan period from the Emirates Stadium runs out tomorrow, but the City boss was giving nothing away about his intentions.

“I’ll decide that – what I’m going to do with him. “Then I’ll chat with Arsenal and I’ll chat with Henri himself,” said Lambert.

The 23-year-old Johnson, meanwhile, will be hoping for the chance to play first team football after making just six appearances for the Canaries this season, all of them as a substitute.

Johnson’s last outing was a brief one as substitute in the 2-0 home defeat by Portsmouth five weeks ago. He scored four times in 17 appearances for the Canaries in League One last season after arriving from Stockport in January.
