While there are some questionmarks in there, his track record is far more sucessful and experienced then any current Polish coach. While I generally have my reservations concerning foreign coaches (I can't help but think back to our last foreign coach- that French dude from the early 60's
) , our last two performances in the WC shows that we need a breath of fresh air and someone to bring us modern football. Hopefully he will appoint Poles as assistants who can learn from his experience and improve the general standard of coaching in Poland.
