Celtic have recruited five players in one day to bolster their squad before Wednesday’s Europa League signing deadline.

The arrivals of teenage Dutch midfielder Joel van den Berg on a four-year deal from PSV Eindhoven and the loan signing of Swiss right-back Jordan Lotomba from Feyenoord were announced after the Scottish Premiership win over Aberdeen.

Earlier in the day, Celtic confirmed loan deals for former England goalkeeper Sam Johnstone and teenage Chelsea duo Shumaira Mheuka and Landon Emenalo.

The Scottish transfer window closes on Thursday (17:00 BST) but for players to be eligible for continental competition, they needed to be registered on Wednesday.

Lotomba, who made 28 appearances for Feyenoord last term, joins on a temporary deal until the end of the season.

Van den Berg signed a four-year deal with the option of a further year and was at Celtic Park for the 3-0 win over Aberdeen.

Johnstone, 33, arrives from Wolverhampton Wanderers and will provide competition for Finland international Viljami Sinisalo.

Striker Mheuka, 18, has extended his contract at Chelsea until 2031, having made nine outings for the London club.

Four of those came in the 2024-25 Conference League, including his only start. Last season, he captained the Chelsea Under-21 side, scoring 18 goals in 19 games.

Emenalo, 18, also joins on loan from the London club and will offer cover for Kieran Tierney at left-back.

He made 14 Premier League two appearances for Chelsea’s Under-21 team last season and set up three goals in those outings.

Johnstone, who won the last of his four England caps in 2023, made 17 appearances last season but lost his starting place at relegated Wolves in December and has not played since an FA Cup loss to Liverpool in early March.

“I’m buzzing to be here and I’m excited to get going,” said the goalkeeper, who began his career at Manchester United and has had spells at Aston Villa, West Bromwich Albion and Crystal Palace.

“I didn’t need convincing by anyone, but Joe Hart rang me the other day just to reiterate what a place this is, what a great group of lads and how the fans are unbelievable.

“You hear about the size of the club, but just being here for a day, you notice how big the club is. And the pressure to win, which is what I like – pressure to win, pressure to perform and we all want to win trophies.”

Kasper Schmeichel had been first choice at Celtic since the summer of 2024, but played his last game in February and subsequently retired because of a shoulder injury.

Manager Martin O’Neill said Johnstone would be “a very good addition” and that Mheuka has “great quality”.

O’Neill also said new left-back Emenalo “has many attributes which I think can benefit us”, adding he is “very quick on the ball and, while he can defend, he certainly gets up the pitch into attacking positions too.”
