Brentford boss Thomas Frank admits he needs to buy in January.

Former Denmark international Jonas Lossl has joined on loan from FC Midtjylland until the end of the season with an option to make the move permanent as the club contend with fitness concerns over goalkeepers David Raya and Alvaro Fernandez.

“Historically we almost have never done too much in January, for at least the last five years I've been here. So I don't think it will be a busy transfer window," Frank said.

“I don't just want to bring in numbers. If we want to bring someone in, he needs to fit the role we are looking for.

“He needs to fit the character profile in terms of being a good guy who wants to work hard and be part of our culture. All those things need to get ticked.

“I then say 'these are all done' and then apparently there's also something about price and salary!

“One of the reasons we have a squad is that when we have injuries there are people ready to step in.

“Unfortunately we've been very unlucky with injuries so we have been able to see people stepping in – Charlie Goode and Mads Bech Sorensen at centre-back and Mads Roerslev and Dominic Thompson.

“All of them have done well so we are in a good place, but we are structured and we have a clear strategy.

“Can we get the right player into the right position with the right potential for the right price? Then we do it, which is difficult sometimes."
