Because Southampton are doing a great job defending and stopping united using the strengths. Sadly united are not playing great but even on form I think they would struggle to beat this defense atm. Just matter of time before Southampton players get tired and mistakes may happen.
Rooney in mf is a stupid decision. Has a good game against relegation fodder and starts being compared to Scholes. Come against a decent team and his poor touch becomes a issue
With that crap formation lvg insists with its no surprise we've lost.
