An interesting decline to watch at the moment is that of Stoke City, whose tough defense has simply fallen apart right in front of them over the past few weeks.
Through the opening 19 weeks of the year, the Potters were virtually unbreakable at the back—particularly when playing at the Britannia, but also away from home.
Their 19 fixtures had yielded just 14 goals against them, giving them the lowest goals against record in the league by a clear margin.
However, that number became even more incredible when you took into account a 4-2 loss to Manchester United and a 2-2 draw to Wigan Athletic—leaving them with just eight goals against in 17 fixtures throughout the opening half of the season.
Yet once the second half of the season started, Stoke's tough defense fell away, with the Potters conceding 13 goals in their last four matches alone. Swansea City ran in three of those this weekend, with Tony Pulis' side not even looking like threatening to stop the Swans' attack at times.
19 weeks, 14 goals against. Last four weeks, 13 goals against.
Stoke City are falling apart at the back.
