Burnley and former Luton striker Andre Gray is undergoing a medical at Watford ahead of signing for a club record fee.

The 26-year-old scored nine Premier League goals for the Clarets last season, his first in the top flight, but turned down a new contract at Turf Moor during the campaign.

The Watford Observer understands the deal will represent a club record fee, which currently stands at just over £12 million for Isaac Success - but is slightly lower than the £18.5 million mentioned in the national press.

The transfer may cause concern for the likes of captain Troy Deeney, given Silva's penchant for operating with a lone striker and the expectation for Gray to feature heavily in attack given the sizeable fee paid out.

Further down the pecking order, Jerome Sinclair - started by Marco Silva in two of his pre-season friendlies - will be assessing his options after likely being relegated to fourth, if not fifth choice at Vicarage Road.

Gray has scored 33 goals in 78 appearances with Burnley, after netting 57 times in 111 games for Luton across three seasons.
