Atletico Madrid boss Diego Simeone admits he is set to lose a 'very important footballer' in Kieran Trippier ahead of the defender's proposed move to Newcastle.
Trippier, 31, has arrived in Tyneside to undergo a medical ahead of his lucrative switch to St James' Park.
Sportsmail understands Newcastle have secured an initial £12million deal plus £3million in add-ons for the England right-back, who is set to become the first signing of their new Saudi era.
He has spent the last two-and-a-half years at Atletico since leaving Tottenham, making 83 appearances and winning the Spanish title last season.
