Kevin Phillips claimed that is was “hugely important” that Leeds United signed Robin Koch after the club announced the signing of the Freiburg defender yesterday.

The former Sunderland and West Brom striker, speaking exclusively to Football Insider correspondent Dylan Childs, tipped the Whites to sign another centre-half this summer in addition to the arrival of the 24-year-old.

The club confirmed that on Saturday evening that Koch had put pen to paper on a four-year deal at Elland Road after an “undisclosed fee” was agreed with Freiburg.

Football Insider understands that the fee agreed between the two clubs was in the region of £12million.

The move comes shortly after a club-record deal for Valencia’s Rodrigo Moreno was completed, the striker also put pen to paper on a four-year contract.

When asked by Football Insider for his reaction to the newly-promoted club’s latest signing, Phillips said:

“It was hugely important that they signed a centre-back. The spine of the team is where newly-promoted teams always look to strengthen.

“Not being able to secure Ben White would have been a massive blow but they didn’t put all of their eggs in that basket. You should always have a backup plan and they had something bubbling in the background.

“They could not have gone into the Liverpool with just one experienced centre-half in Cooper. It was hugely important that they brought one in and I would say they need another to help them through the season.”

Speaking yesterday, Koch said: “Marcelo Bielsa was one of the main points for me to join Leeds, I’ve heard from everybody he is one of the best coaches and I’m really looking forward to the first session with the team and the coach.”

The Germany international made 32 appearances in the Bundesliga last season and helped Freiburg finish eight in the table.
