Arsenal's spending won't end with FC Cologne star Lukas Podolski. The Sunday Mirror says there are four major signings on manager Arsene Wenger's shopping list - Ajax defender Jan Vertongen, Germany internationals Podolski and Mario Goetze, of Borussia Dortmund , and Athletic Bilbao's powerful midfielder Javier Martinez.

Arsenal are close to sealing a £12m deal with Cologne for striker Podolski, who is out of contract in June 2013.

Goetze, an attacking midfielder at Borussia Dortmund, will cost around £20m, while a similar fee will land 23-year-old Martinez from Bilbao.

Martinez is a 6ft 3in ­defensive midfielder, who also plays centre-back. He was outstanding in ­Bilbao's 3-2 ­Europa League win over Manchester ­United last week.
