Bring Back Kerrea Gilbert I'd say it was mainly tempo, structure and technical ability. we were a high throttle team back then but didn't really have a lower gear, and the spanish teams were masters of the slow tempo which messed with our approach. also, they deployed dedicated number 10s which gave vieira a marking headache that he wasnt used to, as no-one in england was using 10s that way at the time. guys like pablo aimar and juan carlos valeron (who basically a spanish zizou-lite at the time) made his role in the team much harder. and in terms of structure, there was typically an extra body midfield which left vieira outnumbered. I remember thinking at the time that vieira was unstoppable, then after playing those teams thinking 'ah, there's levels to this shit'
the way Porto played us brought back those old memories of being pick pocketed in europe
