Toumani Diagouraga could be on his way to Leeds, according to Sky sources

Leeds have signed midfielder Toumani Diagouraga from Brentford on a two-and-a-half year deal, according to Sky sources.

Diagouraga has been an ever-present in Brentford's midfield this season, making 27 appearances.

The 28-year-old came to England as a teenager, joining Watford's academy. He was loaned out to Swindon Town, Rotherham and Hereford United, joining the Bulls permanently in the summer of 2009.

A spell at Peterborough United followed, and a loan spell at Brentford, who signed him full-time in July 2010.

He had a brief loan spell at Portsmouth during the 2013-14 season, but he has been a fixture in the team since the club's promotion to the Championship.

Leeds sold Sam Byram to West Ham for £3.7m earlier this week and immediately looked to re-invest some of that fee.

Steve Evans told the club's website: "We've made a couple of offers in writing. We've had feedback on one of those (on Thursday) morning.

"When the president comes out of his meetings he'll be active on that. There's another one we're waiting to hear back from, but we're actively pursuing another couple.

"To supporters, it may look like 'Sam goes out and nothing comes in', but the reality is far from it.

"The Sam Byram money is available right now, but we have to bring in the right players. We've earmarked targets and, whether it be now or the summer, we will try and sign these players.

"Two or three of the names have never been mentioned in the press, which is positive, and shows that the conversations have remained between me and the president.

"There's no doubt we want to add players who can make a difference but I can't succumb to pressure from the outside."
