I fail to see what is so impressive about fighting relegation each year only to show up in the final weeks of the season. Its not like they have done what swansea have by selling and reinvesting. And wigan have made more profit from sales than swansea
Thats unfair man, with the resources hes operating with, the kind of players he has playing for him, and the fact that every semi decent player he unearths from nowhere gets attracted by other clubs, he's done a great job to actually keep Wigan in the EPL all this time. You're being way too unfair on him imo.
You do realise that it was Martinez that started Swansea playing football that way, he started the academy playing that way. All other managers since him, have taken what he did, and added to it.
