Jackett wants to keep Arsenal's Jay Simpson and Blackburn's Bryan Hodge, as well as Marcus Bignot, on loan from QPR, and Luton's Ahmet Brkovic.

The Lions boss told his club's website: "They have all been key players.

"In Jay's case it seems Arsenal are happy for him to stay here until the end of the season and I'm hopeful of sorting something out for the others."

On possible other transfers, Jackett added: "Aside from those four, if there are players who will complement or directly improve our squad then I will look to bring them in."
