David Raya has already got his gloves on one piece of silverware, and will look to do so again when Brentford start their play-off campaign against Swansea City this evening (6.30pm).

The Bees missed the chance to seal automatic promotion, losing both of their final two matches having won eight matches in a row in their pursuit of West Brom, to finish third.

Thomas Frank’s side will now have to lift themselves ahead of today’s play-off semi-final against a Swansea City side who crept in to the top six on the final day as Nottingham Forest imploded.

Raya this week shared the Championship’s Golden Glove for the number of clean sheets this season, 16 in all, tied with Millwall’s Bartosz Bialkowski. Only champions Leeds United conceded fewer goals than Brentford, whose tightened-up defence was key to their automatic promotion bid, having finished ninth last season.

Raya was a key part of an improved defensive unit, signed in July last year having been identified as the Bees’ first choice to replace Daniel Bentley, who moved on to Bristol City.

The deal that saw the 24-year-old leave Ewood Park was for an undisclosed fee, understood to be in the region of an initial £3m, but there are odds-on included in the deal which could take that closer to £5m.

Rovers would be due a further payment from the Bees should they clinch promotion, so will be eagerly monitoring their progress in the play-offs, with Fulham and Cardiff City squaring up in the second play-off match.

Raya’s form has seemingly not gone unnoticed, with Arsenal and Manchester City reportedly monitoring his progress, with a £10m price-tag mooted, of which Rovers would be due a slice should any interest be firmed up.

Raya has a healthy experience in the Championship, despite being just 24, making 144 appearances in the league, and 10 more in cup competitions, and would be a homegrown option for Premier League clubs.

The link to Arsenal is unsurprising, given goalkeeping coach Inaka Cana Pavon made the move to the Emirates from Brentford in the winter. The Spaniard was thought to be a key figure in the Bees’ pursuit of Raya last summer.

It would an historic first promotion to the Premier League for Brentford who will pay an emotional goodbye to Griffin Park as they prepare to move in to their new stadium for the 2020/21 campaign, whichever division they are in.

Finishing 11 points clear of sixth-placed Swansea, they will hope there is no hangover from the final day disappointment, where victory over Barnsley would have seen them promoted automatically.

Indeed, any funds received from a possible promotion for Raya could help finance his eventual permanent replacement.

Rovers are now without a senior goalkeeper on their books after Christian Walton returned to parent club Brighton having been an ever-present between the sticks during his season-long stay.

Walton appeared in every minute of the 46 Championship matches, a record matched by Raya, while understudy Jayson Leutwiler departs after three years at the club in which he made just 13 appearances.

The Canadian is likely to seek first-team football after three years as back-up to first Raya, and then Walton.

That leaves Andrew Fisher, who spent last season on loan with Northampton Town and MK Dons, and Joe Hilton, signed from Everton last summer, as the most senior of Rovers’ Academy options.

Jordan Eastham travelled with the squad to Luton, with Leutwiler left out, and was named among the substitutes having signed a two-year professional deal earlier this month.

The transfer window re-opens on Monday, with Rovers in the market for two new stoppers, ahead of the new season which begins in under seven weeks.

David Cornell, who left Northampton Town earlier this month, was a target for Rovers in January and could come in to consideration again.

Charlton's Dillon Phillips has had a good season between the sticks for the Addicks, despite relegation, and could attract Championship interest.

Speaking of his goalkeeping department last week, Mowbray said: “Let’s wait and see what the summer brings, that’s a process we’ve been going through, staying late after training sometimes watching videos and the clips of player we think might be able to fit in and then speaking to their advisors and their clubs.

“Nobody has been committal during this period, a lot are saying let’s see what the picture of the football world is when we get to the end of this season.

“What we do know is that the goalkeeping department is something at our football club that will change quite dramatically and we’ll try and get it right.”
