Steve Froggatt is on standby to become the latest left back to try to stifle David Beckham’s vital contribution to the Manchester United cause.

Froggatt, normally a winger, is the man most likely to take over while David Burrows serves a three match suspension.

Burrows, one of the most durable left backs in the country, was automatically banned for being sent off for violent conduct in the recent premiership match at Leicester City.

He also misses the matches at Sunderland and at home to Leeds United.

Coventry’s manager Gordon Strachan has to decide who takes over. He has Marcus Hall back in full training after a serious knee injury and he could switch Richard Shaw to full back and bring in the Bosnian centreback Mo Konjic.

But the manager has been so impressed with Shaw and Paul Williams at centreback that he is unlikely to break up their partnership. The way therefore looks clear for Froggatt to become the latest to try to stop Beckham flighting over his dangerous centres from the right wing.

Froggatt impressed when he went on as substitute against Derby County on Saturday and he laid on the second goal for his former Wolves’ team mate Robbie Keane.

Keane, scorer of both Coventry goals against Derby County, says he cannot wait to pit himself against United.

"This is what I wanted to come into the Premiership for," said the Irish teenager. "Big matches like this are what it is all about and I cannot wait. It will be a full house and the atmosphere will be electric."

Coventry hope they are catching United at just the right time. Sir Alex Ferguson’s side beat Arsenal yesterday but had to send on their third string goalkeeper when the No.2 Raimond van der Gouw, deputising for the injured Mark Bosnich, was carried off with a fractured cheekbone.
