Eintracht Frankfurt has signalled its interest in left-back Mika Haas from 1. FC Kaiserslautern. The 20-year-old homegrown player, who has established himself as a regular this season, is on the Champions League participant's list, according to 'sge4ever.de'. At FCK, Haas plays as a left wing-back but can also function as a traditional left-back. The German U20 international, who extended his contract in June, could fill a gap in Frankfurt's squad, which lacks a second specialist for the left-back position behind Nathaniel Brown. While a winter transfer is considered improbable, Eintracht may attempt a move in the summer. According to Transfermarkt, the player's current market value is €1 million.
