"Therefore Wolfsburg excites me. I hope the transfer happens."

Martins has been reportedly linked with a move to Volkswagen Arena as he is strongly tipped to leave Alan Shearer's Championship side.

The 24-year-old had a poor campaign at St. James' Park last season, scoring eight goals in 24 Premier League games before seeing his side get demoted.

It will be difficult for the pacey striker to carve out a regular place with Armin Veh's team though, amid the presence of lethal strike partners Edin Dzeko and Grafite.
