FA Cup: Round 3 ReplayTodayArsenal vs Swansea City 21:45 SS3Man Utd vs West Ham 22:00 SS5LONDON: Manchester United manager Alex Ferguson plans to rest a number of key players for Wednesday’s FA Cup replay with West Ham United as the English giants eye a treble success.Seven points clear at the top of the Premier League and with an eagerly-awaited last 16 Champions League encounter with Real Madrid on the horizon, United will book a fourth round home tie with Fulham or Blackpool if they overcome the Hammers at Old Trafford.Although Ferguson is unlikely to admit it, West Ham’s visit is a game United could do without.Not only is it his team’s 32nd game of the campaign, it is United’s sixth match in little over three weeks. The schedule does not get any easier for the foreseeable future.Should they overcome West Ham, United face five league and cup games before they travel to Spain to take on Real Madrid on February 13."I shall continue to juggle my squad because although December was a busy month, there is still no let-up,” said Ferguson.
