Arsenal boss Arsene Wenger faces having to shelve interest in Borussia Dortmund fullback Lukasz Piszczek.

The Daily Star says reports in Germany say Wenger went to watch Dortmund at the Gunners' training ground on Saturday, prior to their Champions League defeat by Bayern Munich at Wembley.

And £12m-rated Piszczek was the man Wenger had a close eye on.

The 27-year-old Poland international was a regular in the Dortmund team that did so well in Europe's top club competition. But it has emerged Piszczek needs a hip operation this summer and it is feared he could be out of action for five months.
