#4 Alexis Mac Allister
While Moses Caicedo received the most attention during the January transfer window after publicly requesting permission to leave Brighton & Hove Albion, Alex Mac Allister is another midfielder from Brighton who is being watched by top European teams.
The 24-year-old midfielder has been crucial for Brighton & Hove Albion this season. Despite playing in a pivot alongside Caicedo, he has contributed seven goals in 19 appearances for the club.
He was selected in Argentina's 26-man World Cup squad due to his outstanding performances for the club. Mac Allister was brilliant in Qatar for his national team, helping Argentina capture the trophy after defeating the defending champions, France, in a penalty shoot-out.
With Brighton, who are sixth in the PL and have also eliminated Liverpool in the FA Cup fourth round, the Argentine midfield maestro has maintained his excellent form post-World Cup.
Due to the fact that Alexis Mac Allister still has a long career ahead of him, Manchester United would be wise in making a move for the Argentine. To price him away from the Seagulls, however, would require a sizable sum of money, given the state of the market.
