if games stopped at half time we would be 3rd http://stats.football365.com/dom/ENG/D1/fsthalf.html but then we fold in the second half http://stats.football365.com/dom/ENG/D1/sndhalf.html more ENDEAVOUR!!
A couple of points here: We are playing at too high a tempo in the first half and running out of steam in the second. The team as a whole lack "speed-endurance". Tired players are losing concentration and technique suffers. Take your pick!
All three really-can they train any differently so as to maintain first half tempo-if not do we need to modify our high tempo style a bit
