Matt Clarke has been challenged to break into Brighton’s Premier League starting XI.
The centre-back completed his highly-expected switch to the Seagulls from Pompey on Friday.
He moved on an undisclosed fee and penned a four-year deal at Graham Potter’s side.
Failure to be promoted from League One meant it was inevitable Clarke would depart Fratton Park this summer.
A host of clubs were jostling for the former Ipswich man’s signature – including Championship side Stoke City.
But the 22-year-old, who made 175 appearances for Pompey following his arrival in 2015, opted for the Amex Stadium.
Clarke now faces the difficult challenge of breaking into Potter’s line-up.
Shane Duffy and Lewis Dunk are Brighton’s regular centre-back partnership.
The duo were key when the Seagulls secured promotion into the Premier League in 2016 and have helped them retain their top-flight status for the past two campaigns.
Dan Burn and Leon Balagun are the club’s other options in central defence.
Potter is a huge admirer of Clarke and is delighted to have prised him to West Sussex.
Now the new boss has throw down the gauntlet for the cultured left-footer to dislodge either Duffy or Dunk.
Potter told his club’s website: ‘We are pleased to welcome Matt to the club.
‘He’s an imposing central defender and had a very impressive spell with Portsmouth and has been a key player for them.
‘At 22, Matt has already played a good number of games in the EFL and we are really looking forward to working with him.
‘His challenge now is to compete with our existing centre-halves — an area where we have a lot of competition — and break into our first team.’
Ipswich will get 20 per cent from the fee Pompey receive for Clarke.
