Carlos Corberan on why Huddersfield Town signed Alex Vallejo

The ex-Spanish Under-19 international has signed a one-year contract with the Terriers, with Corberan having been keen to recruit another specialist defensive midfielder to share the workload with Jonathan Hogg.

The 28-year-old defensive midfielder has plenty of experience in La Liga 2, having played for RCD Mallorca, Córdoba CF and most recently CF Fuenlabrada.

Vallejo will not be involved in Tuesday night's home game with Derby County, while he continues to assilimate at his new club and gets up to speed with the demands of Corberan.

Corberan said: "He was something that we always needed in the team, especially in the Championship with the number of games we are playing in a short period of time.

"We need to have two players in each position and the only position where we didn't have two players was in the holding position.

"The idea was to have cover as we know for Hogg and every player that it is hard to play a lot of consecutive games in a row, with the demands of the Championship. Every game is very, very demanding.

"Hogg was the only player who did not have this option. Of course, other players can play in this position, but we did not have any specific midfielder who can cover Hogg when he is not ready to play and that was the idea of the (Vallejo) signing.

"Now, the only (current) player who does not have this option is (Fraizer) Campbell because Danny Ward continues to be out."

Corberan will assess loan keeper Joel Pereira (back) on Tuesday morning to see if he can take his place on the bench for the game against Derby.

Danny Ward is continuing to do well in his fitness work and recovery from a hamstring problem which has put his second Town debut on hold. But he will again not be involved on Tuesday.
