Bolton Wanderers have reportedly launched a second bid of £7m for Crystal Palace starlet Wilfried Zaha.

It emerged this morning that the Trotters have stepped up their pursuit of the 19-year-old with a bid, which was knocked back by the Championship side.

It appears that Bolton boss Owen Coyle has refused to give up and has tabled an improved offer for the highly-rated winger, according to BBC Sport.

Reports have suggested that Palace are waiting for potential approaches from other clubs that are interested in the teenager.

The player has reportedly attracted interest from the likes of Newcastle United and Liverpool.
